Evolution and Observable Properties of Rocky Planet Atmospheres
Marie-Luise Steinmeyer, Lena Noack, Philipp Baumeister +9
The atmospheric composition of rocky exoplanets offers an important tool for constraining the properties of the interior of this type of planet, beyond what is possible from measur…
High-Latitude Zonal Jets in the Martian Upper Atmosphere Driven by Non-Orographic Gravity Waves
Jiandong Liu, François Forget, Ehouarn Millour +2
We investigate thermosphere responses to non-orographic gravity waves (GWs) using wind measurements from the Neutral Gas and Ion Mass Spectrometer onboard the Mars Atmosphere and V…
A Stochastic Parameterization of Non-Orographic Gravity Waves Induced Mixing for Mars Planetary Climate Model
Jiandong Liu, Ehouarn Millour, François Forget +2
This paper presents a formalism of mixing induced by non-orographic gravity waves (GWs) to integrate with the stochastic GWs scheme in the Mars Planetary Climate Model. We derive t…
Planetesimal gravitational collapse in a gaseous environment: Thermal and dynamic evolution
P. Segretain, H. Méheut, M. Moreira +3
Planetesimal formation models often invoke the gravitational collapse of pebble clouds to overcome various barriers to grain growth and propose processes to concentrate particles s…
Star-Planet Interactions in the Radio Domain: Prospect for Their Detection
Philippe Zarka
All types of interaction of a magnetized plasma flow with an obstacle (magnetized or not) are considered, and those susceptible to produce a radio signature are identified. The rol…
Narrow loophole for H2-dominated atmospheres on habitable rocky planets around M dwarfs
Renyu Hu, Fabrice Gaillard, Edwin Kite
Habitable rocky planets around M dwarfs that have H2-dominated atmospheres, if they exist, would permit characterizing habitable exoplanets with detailed spectroscopy using JWST, o…
