Ross 458c: Gas Giant or Brown Dwarf?
William W. Meynardie, Michael R. Meyer, Ryan J. MacDonald +10
Ross 458c is a widely separated planetary mass companion at a distance of 1100 AU from its host binary, Ross 458AB. It is a member of a class of very low-mass companions at distanc…
Habitability in 4-D: Predicting the Climates of Earth Analogs across Rotation and Orbital Configurations
Arthur D. Adams, Christopher Colose, Aronne Merrelli +2
Earth-like planets in the circumstellar habitable zone (HZ) may have dramatically different climate outcomes depending on their spin-orbit parameters, altering their habitability f…
History and Habitability of the LP 890-9 Planetary System
Rory Barnes, Laura N. R. do Amaral, Jessica Birky +42
We present numerous aspects of the evolution of the LP 890-9 (SPECULOOS-2/TOI-4306) planetary system, focusing on the likelihood that planet c can support life. We find that the ho…
Modeling Spitzer 3.6 and 4.5 m Eclipse Depths for the Inflated Hot Jupiter in the Evolved Binary System HD 202772
Arthur D. Adams, Kimberly Bott, Paul A. Dalba +9
As an inflated Hot Jupiter orbiting an early-type primary star in the evolved binary HD 202772 system, HD 202772 A b's presence invites a study of how such a planet forms and evolv…
Turning Earth into Venus: A Stochastic Model of Possible Evolutions of Terrestrial Topography
Arthur D. Adams, Greg Laughlin
Venus may have had both an Earth-like climate as well as extensive water oceans and active (or incipient) plate tectonics for an extended interval of its history. The topographical…
