2. EPSC Meeting 2021, 13-24 Septembre 2021, Virtuel
Chers collègues,
Nous vous invitons à soumettre vos contributions pour le prochain EPSC Meeting qui est organisé de façon virtuelle, du 13 au 24 Septembre 2021 (https://www.epsc2021.eu).
La date limite pour soumettre vos contributions est fixée au 26 May 2021, 13:00 CEST.
Nous attirons l’attention sur les sessions relatives aux exoplanètes, en particulier la session :
EXO3 : Exoplanet observations, modelling and experiments : Characterization of their atmospheres
The field of extrasolar planets is one of the most rapidly changing areas of astrophysics and planetary science. Ground-based surveys and dedicated space missions have already discovered more than 4000 planets with many more detections expected in the near future. A key challenge is now the characterisation of their atmospheres in order to answer to the questions : what are these worlds actually like and what processes govern their formation and evolution ?
To answer these questions, a broad range of skills and expertise are required, stretching from Solar System science to statistical astrophysics, from ground-based observations to spacecraft measurements, and atmospheric/interior/orbital modelling. The numerous studies conducted in the past twenty years have unveiled a large diversity of atmospheres, from ultra-hot Jupiters to temperate super-Earths. The next generation of space and ground based facilities, including current high-resolution instruments (e.g. ESPRESSO, Spirou, CHEOPS, IGRINS, E-ELT, JWST, and Ariel) will characterise this multifarious population in stunning detail and challenge our current understanding. Both theoretical works and experimental measurements are required to prepare for such a change of scale.
This session will focus on the atmospheric characterisation of exoplanets and the conveners welcome any abstract related to this subject.

3. Future instruments to detect and characterise extrasolar planets and their environment, EPSC 2021, EXO7
Dear colleagues, we would like to bring to your attention the following session that will take place during the Europlanet Science Congress 2021 (EPSC2021, https://www.epsc2021.eu), as part of the "Exoplanets and Origins of Planetary Systems" and "Missions, Instrumentation, Techniques, Modelling (MITM)" programmes :
"Future instruments to detect and characterise extrasolar planets and their environment, EPSC 2021, EXO7"
Link : https://meetingorganizer.copernicus.org/EPSC2021/session/41610
Exoplanets are being discovered in large numbers thanks to recent and ongoing surveys using state-of-the-art instrumentation from the ground and from space. In the next years, new astronomical instruments will further scout our Galaxy to overcome the current observational biases in the search of alien worlds, to gain a deeper understanding of the chemical and physical properties of both exoplanets and their environments, and to unveil the processes of formation and evolution of planets and their atmospheres.
The goal of this session is to bring together the instrumentation and observational communities that are underpinning the future of this field. Contributions are invited to review ongoing programmes of exoplanet and circumstellar discs discovery and characterisation, to update on the progress of planned instrumentation programmes, and to present innovative ideas for future instrumentation.
The deadline for abstract submission is 26 May 2021, 13:00 CEST.
Please note that EPSC2021 will be held as a virtual meeting.
Best Regards,
Camilla Danielski, Elodie Choquet, Paul Eccleston, Enzo Pascale, Subhajit Sarkar

4. Synergies between techniques for characterising exoplanets from space and ground-based facilities, EPSC 2021, EXO5
Dear colleagues,
we would like to bring to your attention the following session that will take place during the Europlanet Science Congress 2021 (EPSC2021, https://www.epsc2021.eu), as part of the "Exoplanets and Origins of Planetary Systems" and "Missions, Instrumentation, Techniques, Modelling (MITM)" programmes : "Synergies between techniques for characterising exoplanets from space and ground-based facilities, EPSC 2021, EXO5"
Link : https://meetingorganizer.copernicus.org/EPSC2021/session/41611
The characterisation of exoplanets is among the most active and rapidly advancing fields in modern astrophysics. An increasing number of observing techniques have enabled the characterisation of exoplanet system properties and provided access to the planetary atmospheres (chemical composition, thermal state and dynamics). Recently, combined analyses using different types of observations have outperformed the standard approaches, e.g. enabling precise constraints on the chemical abundances and elemental ratios in their atmospheres, or measurements of both the star and planet spin-orbit angles.
The goal of this session is to inspire the cooperation between specialised teams to overcome the limits of the fragmented data analyses and to break degeneracies in their interpretation. Contributions are invited to present new methods and/or analyses that combine different kind of observations for comprehensive exoplanet characterisation.
The deadline for abstract submission is 26 May 2021, 13:00 CEST.
Please note that EPSC2021 will be held as a virtual meeting.
Best Regards, Giuseppe Morello, Camilla Danielski, Pierre-Olivier Lagage, Lisa Nortmann, Enric Palle, Fei Yan

5. 3eme édition estivale de l’association SpaceBus France
L’association SpaceBus France est à la recherche d’animateurs bénévoles pour faire découvrir l’astronomie au grand public du 19 juillet au 13 août 2021.
Le principe est d’animer un événement autour de l’astronomie dans une ville différente chaque jour pendant 3 semaines. Nous nous installons sur des places publiques pour présenter une dizaine d’animations et faire ainsi découvrir l’astronomie au grand public.
Les deux premières éditions ont attiré près de 18 000 personnes le long des côtes de la Méditerranée et de l’Atlantique. Pour notre troisième édition, nous arpenterons les côtes de la Manche entre Rennes et Val de Reuil du 19 juillet au 13 août. Le trajet sera découpé en 3 circuits d’une semaine environ. Nous avons besoin d’une douzaine de bénévoles pour chaque circuit.
Pour information, les animations et observations ont lieu de 14h à 19h et de 21h à 23h. Pour découvrir nos animations et les éditions précédentes, vous pouvez consulter notre site internet :
https://spacebusfr.wixsite.com/spacebusfrance
ou regarder la vidéo de présentation :
https://www.youtube.com/watch ?v=2CAIFtp0wDg
Pour vous inscrire, merci de remplir le formulaire d’inscription :
Les interventions sont sur la base du bénévolat. Toutes les dépenses sur place ainsi que le trajet sont pris en charge par SpaceBus France.
La tenue de l’événement est bien entendu soumise aux décisions du gouvernement et nous ferons tout pour vous accueillir ainsi que le public dans les conditions les plus sereines.
Nous restons à votre disposition si vous avez des questions et nous espérons vous voir nombreux venir profiter de cette formidable expérience humaine !
L’équipe SpaceBus France
