Clouds as the driver of variability and colour changes in brown dwarf atmospheres
Lucas Teinturier, Benjamin Charnay, Aymeric Spiga +1
Brown dwarfs are massive, giant exoplanet analogues subject to variability and colour changes, known as the L/T transition, fundamental for their thermal evolution. The drivers of…
The effect of near-surface winds on surface temperature and dust transport on Venus
Maxence Lefèvre, Sébastien Lebonnois, Aymeric Spiga +1
The knowledge of the Venus near-surface atmosphere is sparse. Few spacecrafts landed on the surface and measured winds with amplitudes below 1 m/s. The diurnal cycle of the wind am…
Towards sustainable space research in France
Alexandre Santerne, Héloïse Meheut, Didier Barret +8
During the 2024's quinquennial scientific roadmap of CNES, a specific group worked on setting recommendations to decrease the environmental footprint of space science activities. T…
Diurnal and Seasonal variations of Gravity Waves in the lower atmosphere of Mars as observed by Insight
J. Hernández-Bernal, A. Spiga, A. Chatain +2
We investigate Gravity Waves (GWs) in the lower atmosphere of Mars based on pressure timeseries acquired by the InSight lander. We compile a climatology showing that most GW activi…
