Martin Turbet – Le modèle « générique » de climats planétaires et panorama de ses applications @ B18N, Salle Univers
Oct 4 @ 11 h 00 min – 12 h 00 min
Séminaire

Speaker : Martin Turbet

Title: Le modèle « générique » de climats planétaires et panorama de ses applications

Abstract:   Le modèle générique de climats planétaires ou « Generic PCM » est un code communautaire, développé principalement et historiquement au LMD, et dont l’objectif est de simuler l’ensemble des processus physiques et chimiques opérant dans les atmosphères planétaires. Ses applications sont nombreuses : étude de la dynamique atmosphérique de Jupiter, Saturne et des géantes glacées, formation de brumes photochimiques sur Titan, évolution couplée de l’atmosphère et des glaces sur Pluton et Triton, paléoclimats de Mars, la Terre et Vénus, climats et observabilité des exoplanètes (des plus froides et petites aux plus grandes et chaudes), etc.
Après un bref aperçu du modèle et des briques qui le constituent, je vous présenterai un panorama de ses applications, avec une attention toute particulière sur les planètes et exoplanètes telluriques.

Louis Amard – The evolution of young low-mass stars : focus on rotation and activity @ B18N, Salle Univers
Oct 11 @ 11 h 00 min – 12 h 00 min
Séminaire

Speaker : Louis Amard

Title: The evolution of young low-mass stars : focus on rotation and activity

Abstract: Between its formation stage as an active accreting seed and today, the Sun underwent large structural changes as well as variation in magnetic activity, rotation rate and its relation to the surrounding environment. I will go through the different processes that are responsible for these changes and present our latest results on the subject. We will go from the early interaction between the star and its proto-planetary disc bathing in UV radiations emitted from the massive neighbours, to the internal mixing happening in the inner layers of solar-like stars and probed by asteroseismology. Finally, I will try to review the possible applications of this work to other types of stars at different stages of the evolution in the context of the current or future surveys.

Olivia Venot – On the importance of chemical data for warm exoplanet atmospheres @ B18N, Salle 306
Oct 25 @ 11 h 00 min – 12 h 00 min
Séminaire

Speaker : Olivia Venot (LISA)

Title: On the importance of chemical data for warm exoplanet atmospheres

Abstract: The very first data from JWST are finally arriving and show us the full potential of this telescope for the characterisation of exoplanet atmospheres. The interpretation of these data relies on atmospheric models, so it is of paramount importance that these models are reliable and robust. In this context I will show you the methodology applied to develop kinetic models adapted to the atmospheres of hot exoplanets, with physico-chemical data at high temperatures. I will also talk about the Hot Jupiter WASP-43b and the insights that JWST can give us into its atmosphere.
