Magma Ocean Waves and Thermal Variability on Lava Worlds
Mohammad Farhat, Eugene Chiang
Lava worlds are rocky planets with dayside skins made molten by stellar irradiation. Tidal heating on these shortest-period planets is more than skin deep. We show how orbital ecce…
An analytical framework for atmospheric tides on rocky planets. I. Formulation
Pierre Auclair-Desrotour, Mohammad Farhat, Gwenaël Boué +1
Atmospheric thermal tides arise from the diurnal contrast in stellar irradiation. They exert a significant influence on the long-term rotational evolution of rocky planets because…
Interior redox state effects on the stability of secondary atmospheres and observational manifestations: LP 791-18 d as a case study for outgassing rocky exoplanets
Leonardos Gkouvelis, Francisco J. Pozuelos, Thomas Drant +3
Recent advances in space and ground-based facilities now enable atmospheric characterization of a selected sample of rocky exoplanets. These atmospheres offer key insights into pla…
Tides on Lava Worlds: Application to Close-in Exoplanets and the Early Earth-Moon System
Mohammad Farhat, Pierre Auclair-Desrotour, Gwenaël Boué +2
Understanding the physics of planetary magma oceans has been the subject of growing efforts, in light of the increasing abundance of Solar system samples and extrasolar surveys. A…
Thermal tides on rocky planets through a novel fully analytical solution
Pierre Auclair-Desrotour, Mohammad Farhat, Gwenaël Boué +2
Thermal tides are atmospheric tides caused by variations in day-night insolation, similar to gravitational tides but with key differences. While both result in delayed mass redistr…
Tidal evolution of Earth-like planets in the habitable zone of low-mass stars
E. F. S. Valente, A. C. M. Correia, P. Auclair-Desrotour +2
Earth-like planets in the habitable zone of low-mass stars undergo strong tidal effects that modify their spin states. These planets are expected to host dense atmospheres that can…
