Coupled Orbital and Interior Evolution of Sub-Neptunes
The Astrophysical JournalRecent observations have yielded the first measurements of young exoplanet demographics. Close-in sub-Neptune occurrence rates appear to rise from young (10–100 Myr) to intermediate (100 Myr–1 Gyr) ages and then decline sharply in the old (≳1 Gyr) Kepler

Tidally Driven Inertial Waves Enhance Eccentricity Damping and Spin Evolution in Planets and Stars
The Astrophysical JournalTidal interactions influence the orbital motions of binary star systems and extrasolar planets alike. Tides also affect stellar and planetary rotation rates.

The Feasibility of Asynchronous Rotation via Thermal Tides for Diverse Atmospheric Compositions
The Planetary Science JournalThe equilibrium rotation rate of a planet is determined by the sum of torques acting on its solid body. For planets with atmospheres, the dominant torques are usually the gravitational tide, which acts to slow the planet’s rotation rate, and the ...

Tidal dissipation in rotating and evolving giant planets with application to exoplanet systems [PDF]
We study tidal dissipation in models of rotating giant planets with masses in the range 0.1–10MJ throughout their evolution. Our models incorporate a frequency-dependent turbulent effective viscosity acting on equilibrium tides (including its ...

Metal Pollution in Sun-like Stars from Destruction of Ultra–short-period Planets
The Astrophysical Journal LettersChemical evidence indicates that an appreciable fraction of Sun-like stars have engulfed rocky planets during their main-sequence lifetimes. We investigate whether the tidal evolution and destruction of ultra–short-period planets (USPs) can explain this ...

Magma Ocean Waves and Thermal Variability on Lava Worlds
The Astrophysical JournalLava worlds are rocky planets with dayside skins made molten by stellar irradiation. Tidal heating on these shortest-period planets is more than skin deep.
