Quelques ateliers d'intérêt spécifique pour la communauté PNP:
Atelier Général du PNP : Le Programme National de Planétologie organise un atelier "blanc" couvrant toutes les thématiques Astronomie et Astrophysique couvertes par le PNP. Ces thématiques comprennent :
L'observation et la modélisation de la formation des systèmes planétaires;
L'étude des propriétés des divers objets qui les constituent, exoplanètes, planètes et petits corps;
La compréhension du comportement et de l'évolution des objets individuellement, et des systèmes planétaires dans leur ensemble.
Pour chacun de ces aspects, des présentations d'études théoriques, observationnelles ou de simulations numériques sont les bienvenues pour présenter à l'ensemble de la communauté française la diversité des travaux réalisés dans tous les thèmes de la planétologie, quelque soit leur approche méthodologique.
Demain l’ELT ! Quelle science dans quel contexte dans les années 2030: Cet atelier multi-PN et pluriannuel propose de préparer la communauté astronomique à l'arrivée de l'Extremely Large Telescope (ELT), qui sera le plus grand télescope optique au monde et dont la première lumière est attendue pour fin 2025. Nous souhaitons en 2021 traiter particulièrement de l’ELT dans le paysage observationnel global à l’horizon 2027-2030.
Joint workshop SFE-PNP: Extraterrestrial materials, samples return missions and implications for Exobiology : In the context of the exogenous delivery of volatiles (water and organic matter) on telluric planets, missions of sample return, essentially from asteroids, as well as the study of meteoritic matter, are considered as of prime importance to assess the possible role of such materials on the emergence of prebiotic chemistry on telluric planets. This joint workshop SFE-PNP will focus on the nature, possible origin and evolution of the organic matter within small bodies of the Solar System. With the recent successes of Hayabusa 1 and 2 and the on-going mission OSIRIS-REx, this decade is opening a new era in analyzing in unprecedented detail in the laboratory reasonably large amounts of primitive materials collected in-situ.
Cinquième réunion des utilisateurs des télescopes français (TBL/OHP193): Bienvenue à la réunion biennale des utilisateurs des télescopes français (TBL/OHP193). Elle vise à faire se rencontrer leurs utilisateurs, et à présenter les évolutions des télescopes et de leurs instruments ainsi que les résultats scientifiques qui y ont récemment été obtenus
Atelier Général de l'AS SKA : SKA, son éclaireur français NenuFAR, et ses précurseurs: SKA permettra des avancées décisives en physique et astrophysique. Cet atelier vise à faire une revue des activités scientifiques et techniques autour de ce projet, que ce soit la science avec SKA, la mise en service récente de son éclaireur français NenuFAR, les activités concernant les précurseurs internationaux comme MeerKAT ou ASKAP, ou les travaux menés autour de la radioastronomie en général
Détecter et caractériser des exoplanètes en présence d’activité stellaire: De nombreuses missions spatiales (PLATO, JWST, ARIEL) et au sol (ESPRESSO, SPIROU) ont pour objectif de découvrir et caractériser des planètes semblables à la Terre. La réussite de cet objectif dépend de notre compréhension des phénomènes d’activité stellaire. Cet atelier propose de réunir la communauté stellaire et d'exoplanétologie afin de discuter de cette problématique, défi de cette décennie.
Relevés photométriques grand champ II: Suite au succès de l'atelier tenu lors de la SF2A 2018 et de l’avancée rapide du sujet, ce second atelier rassemblera de nouveau la communauté française impliquée sur les grands relevés photométriques grand champ optique et proche infrarouge présents (Gaia, DES, DECaLS, HSC, UNIONS-CFIS, etc.) et futurs (Euclid, Rubin-LSST, etc.) pour dresser un bilan de la science et des méthodes.
Magnétosphères (exo-)planétaires comparées : Les résultats et les questions sur la nature et la dynamique des différents types de magnétosphères lors de leur interaction avec leur étoile hôte seront abordés autant que possible durant l'atelier proposé avec une approche comparée, et une large place sera laissée à la discussion pour favoriser les échanges entre les communautés terrestre, (exo-)planétaire, et astrophysique.Les résultats et les questions sur la nature et la dynamique des différents types de magnétosphères lors de leur interaction avec leur étoile hôte seront abordés autant que possible durant l'atelier proposé avec une approche comparée, et une large place sera laissée à la discussion pour favoriser les échanges entre les communautés terrestre, (exo-)planétaire, et astrophysique.
2) Special issue of Space Science Reviews on In Situ Exploration of the Ice Giants: Science and Technology
On 25–27 February, 2019, an international workshop on In Situ Exploration of the Ice Giants: Science and Technology was convened at the Laboratoire d’Astrophysique de Marseille, France. Co-sponsored by CNRS, CNES, and JPL, the workshop was dedicated to scientific and technology topics relevant to future in situ exploration of ice giant planet atmospheres, including the overall need for and requirements of ice giant system exploration in the context of future ice giant, gas giant, solar system, and exoplanetary studies. The Workshop comprised 65 presentations separated into sessions dedicated to the context for ice giant exploration (giant planets, exoplanets, and origins), ice giant atmospheres (composition, structure, and dynamics), ice giant interiors, needed technologies (entry systems, and radioisotope power systems), instrumentation, and mission concept options. A special issue of Space Science Reviews was recently published comprising papers based on presentations and discussions from the Marseille 2019 meeting. The special issue includes timely and comprehensive reviews of the status of science, instrumentation, mission concept, and technology topics relevant to the exploration of ice giant planet atmospheres with entry probes, including key scientific questions, how to achieve them, and technology challenges.

5) Exoplanets PhD positions in Geneva
The exoplanet team of the University of Geneva has an opening for two PhD positions to work on detection and characterization of exoplanets through high-precision radial velocity measurements. Focusing on the low-mass range of exoplanets and using the high-precision spectrographs CORALIE, HARPS, HARPS-N, ESPRESSO, and NIRPS, Geneva exoplanets team is strongly involved in blind radial-velocity surveys as well as in the follow-up of transiting candidates from NGTS, K2 and TESS photometric surveys.
One PhD project, supervised by Prof. François Bouchy, is linked to the study of the properties of transiting planets with a specific focus on warm-transiting planets orbiting low-mass red dwarfs (M-type stars). The PhD student will be involved in the radial velocity follow-up, mass and density measurement of TESS and K2 transiting candidates using HARPS and the Near-InfraRed Planet Searcher (NIRPS), a new near-infrared spectrograph which will be soon installed on the 3.6m ESO telescope. The PhD assistant will be in charge to establish the performances of NIRPS, to select and to vet transiting candidates, to schedule NIRPS observations, to model and analyze the data, and to interpret planets properties.
The second PhD project, supervised by Prof. Stéphane Udry and Prof. Damien Ségransan, is linked to the blind search for exoplanets using the radial-velocity technique with both of CORALIE and NIRPS. First, the PhD assistant will work on the improvement of the detection capacities of the historical CORALIE planet search survey by implementing latest generation of data reduction tools developed in the context of HARPS and ESPRESSO. In addition to monitoring the progresses of the ongoing survey, the candoc will search for giant planets and brown dwarfs on a subsample of active stars for which the data analysis will be fine-tuned. Finally, the candidate will participate to the operations and exploitation of the NIRPS program, in particular to the RV blind search for low-mass planets orbiting M dwarfs.
The selected applicants are expected to work on: the optimization of the data-reduction, calibration and RV-extraction from both visible and near-infrared high-resolution spectrographs; the mitigation of the stellar activity; the combination of RV data with photometric, astrometric and direct imaging measurements, including dynamical developments for the characterization of multi-planetary systems. They will be strongly involved in the science exploitation of large programs and guarantee observing time of aforementioned spectrographs and in the development of specific tools for the Data and Analysis Center for Exoplanets (DACE) 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. The exoplanet team is especially well renown, with strong involvement in planet 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, dedicated to the study of the origin, evolution, and characterization of planets inside and outside our Solar System. The applicant will also have the opportunity to develop collaborations with members of PlanetS.
The applicants are required to have a Master in Astrophysics. Proficiency in Python programming, signal processing and strong interest in data sciences and applied mathematics are considered as a plus. These four-year PhD positions are founded by Swiss National Science Foundation with a gross salary around 50,000 CHF a year. The positions are available 2021 July 1st. The University is actively seeking to increase the numbers of women in physics and hence women are strongly encouraged to apply. Interested applicants should send (in a single pdf file) a curriculum vitae, academic transcripts, a motivation letter including information on skills and previous experience, names of people who can be contacted for a letter of recommendation, and the contact details to Prof. François Bouchy and Prof. Stéphane Udry, at the Astronomy Department of Geneva University, before 10th May 2021.

6) A 2-year postdoctoral position on the VLT/HiRISE project at LAM (France)
HiRISE implements a fiber optics coupling between the exoplanet imager SPHERE and the high-resolution spectrograph CRIRES+. It will enable the characterisation of directly-imaged exoplanets in the H-band with a large expected gain in SNR compared to CRIRES+ in standalone (Otten et al. 2021; https://ui.adsabs.harvard.edu/abs/2021A%26A...646A.150O/abstract). The project is starting its integration and testing phase in Europe before its installation at the VLT in 2022, and the beginning of science observations shortly afterwards.
We are looking for a postdoctoral researcher who will be working with the HiRISE team on the scientific validation of the instrument, on the preparation of the observing program, and on the analysis and interpretation of the first on-sky data. Applications sent before Friday 14 May 2021 will receive full consideration, but the position will remain open until filled. The expected start date is between September and November 2021.
