A multispecies pseudoadiabat for simulating condensable-rich exoplanet atmospheres
R. J. Graham, Tim Lichtenberg, Ryan Boukrouche +1
Central stages in the evolution of rocky, potentially habitable planets may play out under atmospheric conditions with a large inventory of non-dilute condensable components. Varia…
Beyond runaway: initiation of the post-runaway greenhouse state on rocky exoplanets
Ryan Boukrouche, Tim Lichtenberg, Raymond T. Pierrehumbert
The runaway greenhouse represents the ultimate climate catastrophe for rocky, Earth-like worlds: when the incoming stellar flux cannot be balanced by radiation to space, the oceans…
Revealing asymmetrical dust distribution in the inner regions of HD 141569
Garima Singh, Trisha Bhowmik, Anthony Boccaletti +42
We obtained polarimetric differential imaging of a gas-rich debris disk around HD 141569A with SPHERE in the H-band to compare the scattering properties of the innermost ring at 44…
Vertically resolved magma ocean-protoatmosphere evolution: H, HO, CO, CH, CO, O, and N as primary absorbers
Tim Lichtenberg, Dan J. Bower, Mark Hammond +4
The earliest atmospheres of rocky planets originate from extensive volatile release during magma ocean epochs that occur during assembly of the planet. These establish the initial…
