Modeling the albedo of Earth-like magma ocean planets with H2O-CO2 atmospheres
William Pluriel, Emmanuel Marcq, Martin Turbet
During accretion, the young rocky planets are so hot that they become endowed with a magma ocean. From that moment, the mantle convective thermal flux control the cooling of the pl…
Far infrared measurements of absorptions by CH4+CO2 and H2+CO2 mixtures and implications for greenhouse warming on early Mars
Martin Turbet, Ha Tran, Olivier Pirali +3
We present an experimental study of the absorption, between 40 and 640 cm, by CO, CH and H gases as well as by H+CO and CH+CO mixtures at room te…
The nature of the TRAPPIST-1 exoplanets
Simon L. Grimm, Brice-Olivier Demory, Michaël Gillon +23
Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation a…
Measurements and modeling of absorption by CO2+H2O mixtures in the spectral region beyond the CO2 nu3-band head
Ha Tran, Martin Turbet, Pascale Chelin +1
In this work, we measured the absorption by CO2+H2O mixtures from 2400 to 2600 cm-1 which corresponds to the spectral region beyond the nu3 band head of CO2. Transmission spectra o…
