Composition of Terrestrial Exoplanet Atmospheres from Meteorite Outgassing Experiments

Posted by klaurent Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: Maggie A. Thompson, Myriam Telus, Laura Schaefer, Jonathan J. Fortney, Toyanath Joshi | Summary: Terrestrial exoplanets likely form initial atmospheres through outgassing during and after accretion, although there is currently no first-principles understanding of how to connect a planet’s bulk composition to its early atmospheric properties. Important […]
