1) Décès de Franck Shu
Nous avons le regret de vous annoncer le décès de Frank Shu le 22 avril 2023, à l'âge de 79 ans, chez lui à Atherton (Californie). Né à Kunming, en Chine, en 1943, Frank a émigré aux États-Unis avec sa famille à l'âge de 5 ans. Il a obtenu son doctorat à Harvard en 1968 et a effectué la plus grande partie de sa carrière scientifique à l'université de Berkeley. Les contributions de Frank Shu à l’astrophysique théorique sont extrêmement nombreuses ; elles feront date tout comme ses livres : The Physical Universe et Physics of Astrophysics. Au mitan des années 90, ses travaux sur la formation des chondrites ont bouleversé les études des météorites ; ils ont grandement influencé les cosmochimistes du monde entier et en particulier l’école française qui, suivant son exemple, a inlassablement cherché à nouer un dialogue fécond entre astrophysiciens et spécialistes des météorites.

4) 14th International Colloquium on Atomic Spectra and Oscillator Strengths for Astrophysical and Laboratory Plasmas (ASOS) | July 10-13, 2023 | Paris
The 14th International Colloquium on Atomic Spectra and Oscillator Strengths for Astrophysical and Laboratory Plasmas (ASOS) will be held in Paris, from July 10 to 13, 2023, starting with a welcome reception on Sunday July 9th evening. It will be located on the campus « Les Cordeliers » of the Sorbonne University, 15, rue de l'Ecole de médecine, 5th district of Paris, in the heart of the Latin Quarter. A conference dinner is being organised for Wednesday 12th evening. The conference will end at midday on Thursday 13th, 2023. Information will be posted as become available on https://asos2023paris.sciencesconf.org.
The registration for the 14th ASOS is open from now to June 25th 2023, through the website https://asos2023paris.sciencesconf.org.
The aim of the ASOS series of conferences is to bring together scientists from atomic physics, plasma physics and astrophysics and to bring together the “producers” of fundamental atomic data and the “users” of these data. During the conference, atomic physicists present the development of their theoretical and experimental methods, as well as the possibility of obtaining increasingly complete and precise data on the structures, the radiative and collisional properties of atomic systems. Astrophysicists and plasma physicists review the context of their research and their needs for atomic data for modelling the plasmas studied, such as stellar or solar plasmas, fusion plasmas or other laboratory plasmas.
Topics (from previous conferences) :
- Need for atomic data from space and ground observations (solar and stellar plasmas, interstellar media, active nuclei of galaxies, quasars, kilonovae)
- Need for atomic data from laboratory experiments (diagnostics of fusion plasmas, plasmas produced by laser)
- Determination of lifetimes and oscillator strengths
- Hyperfine structures, isotopic shifts
- Theoretical modelling and numerical approaches
- Laboratory techniques
- Ion storage
- High resolution spectroscopy
- Variation of fundamental constants
- Collisional processes
- High energy density plasma spectra, opacities
- Spectral line profiles (broadening, shifts, nuclear effects, magnetic field effects, polarisation)
- Atomic databases and connected subjects

- The detection and characterization of exoplanet systems through high-precision radial velocity measurements (2 positions) contacts for information: Prof. François Bouchy (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.), Prof. Christophe Lovis (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.) and Prof. Xavier Dumusque[1] (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.).
- The detection and characterization of brown dwarfs and exoplanets using high-contrast imaging (1 position) contact for information: Prof. Damien Ségransan (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.).
- The interpretation of spectra of exoplanetary atmospheres obtained at high-spectral resolution (1 position) contact for information: Prof. David Ehrenreich (Cette adresse e-mail est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.)
Using the high-resolution spectrographs CORALIE, HARPS, HARPS-N, ESPRESSO, and NIRPS, our team is strongly involved in blind radial velocity (RV) surveys as well as in the follow-up of transiting candidates from NGTS, K2 and TESS photometric surveys. We further exploit these instruments to characterize the atmospheres of transiting exoplanets, allowing us to resolve chemical species across the surface of exoplanets. In addition, based on our experience with Gaia astrometry and using the historical CORALIE and HARPS radial velocity surveys, we are probing – with the high contrast imager SPHERE – substellar objects at the divide of brown dwarfs and massive giant planets to study the physics of ultra-cool atmospheres and bring constraints on planet formation and evolution theories. The selected applicants are expected to work on (i) the optimization of the data-reduction, calibration and RV-extraction from both visible and near-infrared high-resolution spectrographs; the mitigation of stellar activity using data driven and machine learning techniques; the combination of RV data with photometric, astrometric and direct imaging measurements, including dynamical developments for the characterization of multi-planetary systems; (ii) the development of advanced high contrast imaging algorithm in the context of current SPHERE observations and in preparation of the SAXO+ project; (iii) the development and/or adaptation of forward 3D atmospheric models or retrieval techniques to exploit transit transmission spectra obtained with ESPRESSO in the optical and NIRPS in the near-infrared.
The successful candidates will be strongly involved in the science exploitation of large programs and guaranteed observing time of the aforementioned spectrographs and in the development of specific tools for the Data and Analysis Center for Exoplanets (DACE - https://dace.unige.ch) for validation and combined analysis of exoplanets.
The Department of Astronomy of the University of Geneva offers a modern and vibrant work environment, with a wide range of activities including theory, numerical simulations, observations and instrumental developments in the domains of exoplanets, stellar physics, galactic dynamics, observational cosmology and high-energy astrophysics. Our exoplanet team is well-renowned and has strong involvement in exoplanets detection, the determination of the planet physical properties, the characterization of planet atmospheres, and the development of an associated world-class instrumentation. We are also co-leading the Swiss-wide National Centre of Competence in Research (NCCR) PlanetS (http://nccr-planets.ch), dedicated to the study of the origin, evolution, and characterization of planets inside and outside our Solar System, providing thus the applicants with opportunities to develop collaborations with members of PlanetS.
The duration of the postdoc contracts is for 2 years, with possible extension to a third year depending on available funds. Candidates should have less than 3 years after their PhD at start of the employment. The positions are funded by Swiss National Science Foundation with a gross salary around 80,000 CHF and are open for immediate start.

9) PhD position on Exoplanets | Université de la Côte d'Azur
https://adum.fr/as/ed/voirproposition.pl?site=adumR&matricule_prop=49885#version
Methane is the main carbon-bearer molecule in our solar-system giant planet atmospheres. It has been used to measure the metallicity of these planets, allowing to deepen our understanding of their formation processes. On exoplanets methane is expected to become the dominant carbon-bearer molecule for planets cooler than approximately 1200K. However, it remains elusive. None of the dozen warm exoplanet observed by the Hubble Space Telescope show definitive evidence of methane, despite methane having a very strong absorption band in the WFC3 instrument.
The James Webb Space Telescope began observations off exoplanet atmospheres this summer and is providing spectra of a much better precision than HST and covering a much wider wavelength range. The first planets observed by JWST through the Early Release Science program showed a definitive lack of methane. Other observations from GTO and GO programs all confirm this trend: lower than expected methane abundances are observed in other planets.
Predicting the methane abundance in these planet is a complex problem. These warm, tidally locked planets are not expected to be in thermochemical equilibrium and atmospheric circulation is expected to play a strong role shaping the chemical abundances at the photosphere. Strong vertical mixing can bring methane-rich air from the deep layers of the planet. Once the air reaches the lower pressure levels, methane is expected to photodissociate thanks to the strong UV radiation of the host star. The radicals formed should then combine and form a thick photochemical haze layer that can shield the methane below from being more dissociated. The haze particles should then grow and settle down, bringing back the carbon atoms to the deep, hot atmospheric layers where they can evaporate and form gaseous methane again. The chemical abundances resulting from this methane cycle will be determined by a competition between the vertical mixing needing to bring new gaseous methane upward and the particle settling, leading to a downwelling flux of carbon atoms. The deep atmospheric temperature profile and the atmospheric metallicity, two quantities that we would like to ultimately measure, will both play a fundamental role in setting the background gaseous abundances and the main chemical reaction paths that are available to the chemistry.
The goal of this PhD project is to model the methane cycle on warm exoplanets in order to quantify the expected methane abundance in warm exoplanets and link the observed methane abundances to specific planet parameters, such as metallicity, deep temperature or strength of the vertical mixing. The student will use the 3D, non-grey, atmospheric circulation model SPARC/MITgcm that has already been used to model a diversity of planets, ranging from metal-rich sub-Neptunes (Kataria et al. 2014) to ultra-hot Jupiters (Parmentier et al. 2021) and allows the calculation of spectra that can be directly compared to the observations. The student will combine this model with a chemical network such as the VULCAN model to follow the methane as it is advected and react chemically.
At the same time, the student will work closely with the JWST guaranteed time observation team led by Tom Greene (Program: GTO 1185 https://sites.google.com/view/jwstmanatee/) and in which Vivien Parmentier is an active collaborator to compare his modelling predictions to the observations of 6 different warm Neptunes that will be observed in the coming two years.”

10) Post-doctoral fellowship on 3D radiative transfer modeling on Mars | LATMOS, Guyancourt
Based on an existing radiative transfer model (SHDOM), the candidate will develop a model to simulate the near-infrared radiative environment in which the Perseverance rover is evolving in the context of the Mars 2020 mission. This model will help to better understand the influence of the Martian atmosphere (its gaseous and particular, dust/ice, composition) on the visible and infrared spectra of rocks observed by the SuperCam instrument in which LATMOS is involved.
The candidate will work in the Planetology department of LATMOS, more particularly in a team interested in the composition of the atmospheres of Mars and Venus and very involved in the current space missions (Mars 2020, ExoMars Trace Gas Orbiter, Mars Express, etc).
The candidate will be expected to take several algorithms (radiative transfer, spectroscopic database of rocks and gases; Jezero crater terrain model) and assemble them to develop a complete direct model to most accurately reproduce how solar photons are affected by the atmospheric component depending on where the rover is and what target it is viewing.
The following skills are appreciated:
- Programming in Fortran, IDL, Python or other
- Knowledge in optics
- Basic knowledge of atmospheric physics appreciated, but not imperative.
This contract is funded by CNRS for 15 months (depending on experience).
This position is also suitable for a candidate more interested in the engineering aspects of a research project.

12) Thèse, HDR, séminaires
a) Séminaire | Nicolas Levraud (LAM): Measuring the ELT petal mode in presence of AO residual turbulence with pyramid wavefront sensor | Jeudi 25 Mai, 16h00
https://us02web.zoom.us/j/85481169824
The next generation of Extremely Large Telescope (24 to 39m diameter) will suffer from the so-called "pupil fragmentation" problem. Due to their large spiders, differential pistons will appear in the wavefront between the part of the pupil separated by these spiders during observations.
The Adaptive Optics (AO) system necessary to compensate atmospheric turbulence appears unable to sense this differential piston leading to bad control by the loop. Hence, such differential pistons, a.k.a petal modes, will prevent the AO system from reaching the diffraction limit of the telescope and ultimately will represent the main limitation of AO-assisted observation with an ELT. All the future single conjugated AO systems for the ELT have a PyWFS that is sensible to differential piston unlike the Shack-Hartmann, but it is not trivial to get a good enough sensitivity. This is particularly true for high contrast observing modes. These differential pistons can evolve quickly, so we are looking for an AO loop scheme able to measure both the atmospheric turbulence and the petal modes.
Solutions have been proposed such as the Holographic Dispersed Fringe Sensor (HDFS) for the Giant Magellan Telescope but they are not fast enough to be implemented as WFS of the AO loop and require longer AO sensing wavelength.
In this talk we want to study how to make the Pyramid Wavefront Sensor (PyWFS) sensitive to petal mode with visible light. We show that a small modulation radius makes the PyWFS sensitive to petal but unable to measure atmospheric turbulence due to the PyWFS non-linearities. We therefore propose to add dedicated petal sensor as a 2nd path and we study the unmodulated PyWFS as a candidate for this role. We study the reconstruction of the petal mode present in the residuals by this petalometer. We show that the petal mode due to its spatial frequency distribution beeing infinite can be confused with other high spatial frequency modes present in the residual turbulence. We propose a focal plane spatial filter to reduce high frequency residuals. The spatial filter helps in reducing this confusion, improving the petal measurement. In this talk we perform E2E simulations to demonstrate the validity and performance of this new concept.

As of today, there exists a plethora of post-processing algorithms for exoplanet imaging. Their performance has been assessed using different data sets and metrics, which caused confusion in the HCI community when comparing their detection ability. In order to homogenize the comparison of these algorithms, the Exoplanet Imaging Data Challenge (EIDC) was born. With twenty eight algorithm submissions, the first EIDC phase (exclusively dedicated to exoplanet detection) provided two interesting conclusions: (1) detection algorithms that exploit the local behavior of image noise obtained the highest detection score; (2) supervised machine learning algorithms, such as the SODINN deep neural network developed at ULiège, produced a relatively high number of false positives. With the aim of improving the robustness of SODINN against false alarms, we built a more advanced version, referred to as Noise-Adaptive SODINN, which relies on two new strategies that help the training to capture stronger local image noise correlations. First, unlike its predecessor, NA-SODINN trains an independent classification model per image noise regime in the processed frame. Second, its network is fed with S/N curves, local discriminators that contain additional physical-motivated features and help the trained model to better disentangle an exoplanet signature from speckle noise. NA-SODINN is evaluated against SODINN through a Receiver Operating Characteristics (ROC) analysis, in which we observe a clear improvement in both sensitivity and specificity. Then, it is submitted to EIDC, where we observe that it is ranked at the top (first or second position) of the challenge leaderboard for all considered evaluation metrics.

Astronomical insola-on forcing is now well-established as the underlying metronome of Quaternary ice ages and Cenozoic climate carbon-cycle feedback mechanisms. However, its effects on earlier Eras (Mesozoic, Paleozoic, and pre-Cambrian) are less understood. During this seminar, I will evaluate various pre-Cenozoic modes of response to astronomical forcing, and provide an overview of the Earth System components that were par-cularly sensi-ve to astronomical forcing under evolving boundary condi-ons. Subsequently, the role of astronomical forcing in pacing the global carbon cycle in the Devonian warmhouse and Cretaceous hothouse worlds is discussed. Both periods are characterised by recurrent ocean anoxia and remarkably similar hypotheses exist regarding how astronomical forcing could have amplified a nutrient surplus (from chemical weathering and volcanism, respec-vely) to tip the ocean system into anoxia. The Triassic-Jurassic boundary cyclostratigraphy illustrates the importance of precession-scale time-control to understand feedback mechanisms and cause-and-effect chains at a resolution that is relevant for making analogies with the present- day. Finally, I will provide an outlook on the need for a coordinated approach, using so-called astrochronozones, to establish a fully astronomically-calibrated -mescale for the Phanerozoic. Overall, the aim of the seminar is to highlight the need for a more comprehensive understanding of the role of astronomical insola-on forcing in shaping Earth's climate over geologic time. After all, such comprehensive understanding constitutes a crucial pre-requisite before one can use the geological record to reconstruct solar system fundamental frequencies and Earth-Moon dynamics.

Titre : La mission spatiale Juice est-elle une mission d’exobiologie ?
Résumé :
JUICE est une mission majeure de l'ESA qui va explorer de façon complète Jupiter, ses anneaux et ses lunes dans les années 2030. Le système jovien peut être considéré comme un système solaire miniature, les 4 lunes galiléennes présentant une richesse géologique et une diversité qui n'ont rien à envier aux planètes telluriques. L'objectif de JUICE est d'apporter des éléments de réponse à de grandes questions propres à Jupiter, mais également de plus grande portée. Quels sont les processus physico-chimiques ayant conduit à autant de diversité entre les
