Disentangling the hemispheres of Teegarden's Star b with LIFE
Ryan Boukrouche, Markus Janson
Teegarden's Star is one of the most promising targets for the first observations of LIFE, as a non-transiting rocky planet with similar bulk properties to the Earth, and a relative…
Near the Runaway: The Climate and Habitability of Teegarden's Star b
Ryan Boukrouche, Rodrigo Caballero, Neil Lewis
Teegarden's Star b, a nearby terrestrial world receiving an Earth-like instellation, is a prime candidate for next-generation observatories targeting temperate exoplanets in their…
The impact of water clouds on the prospective emission spectrum of Teegarden's Star b as observed by LIFE
Ryan Boukrouche, Rodrigo Caballero, Markus Janson
Non-transiting terrestrial planets will be accessible by upcoming observatories of which LIFE is an example. Planet b orbiting Teegarden's Star is one of the optimal targets for su…
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…
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…
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…
