The Impact of Turbulent Vertical Mixing in the Venus Clouds on Chemical Tracers
Maxence Lefèvre, Emmanuel Marcq, Franck Lefèvre
Venus clouds host a convective layer between roughly 50 and 60 km that mixes heat, momentum, and chemical species. Observations and numerical modelling have helped to understand th…
On the stability of low-mass planets with supercritical hydrospheres
Hugo Vivien, Artyom Aguichine, Olivier Mousis +2
Short-period and low-mass water-rich planets are subject to strong irradiation from their host star, resulting in hydrospheres in supercritical state. In this context, we explore t…
Water content trends in K2-138 and other low-mass multiplanetary systems
Lorena Acuña, Theo Lopez, Thierry Morel +5
Super-Earths and sub-Neptunes have been found simultaneously in multiplanetary systems, suggesting that they are appropriate to study composition and formation within the same envi…
Near-infrared transmission spectrum of TRAPPIST-1 h using Hubble WFC3 G141 observations
A. Gressier, M. Mori, Q. Changeat +4
The TRAPPIST-1 planetary system is favourable for transmission spectroscopy and offers the unique opportunity to study rocky planets with possibly non-primary envelopes. We present…
Day-night cloud asymmetry prevents early oceans on Venus but not on Earth
Martin Turbet, Emeline Bolmont, Guillaume Chaverot +3
Earth has had oceans for nearly four billion years and Mars had lakes and rivers 3.5-3.8 billion years ago. However, it is still unknown whether water has ever condensed on the sur…
Mass-radius relationships for irradiated ocean planets
Artyom Aguichine, Olivier Mousis, Magali Deleuil +1
Massive and water-rich planets should be ubiquitous in the universe. Many of those worlds are expected to be subject to important irradiation from their host star, and display supe…
