Tidal Synchronization Trapping in Stars and Planets with Convective Envelopes

open access: yesThe Astrophysical Journal
Tidal torques can alter the spins of tidally interacting stars and planets, usually over shorter timescales than the tidal damping of orbital separations or eccentricities.

The Feasibility of Asynchronous Rotation via Thermal Tides for Diverse Atmospheric Compositions

open access: yesThe Planetary Science Journal
The 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 ...

Tidally Driven Inertial Waves Enhance Eccentricity Damping and Spin Evolution in Planets and Stars

open access: yesThe Astrophysical Journal
Tidal interactions influence the orbital motions of binary star systems and extrasolar planets alike. Tides also affect stellar and planetary rotation rates.

Metal Pollution in Sun-like Stars from Destruction of Ultra–short-period Planets

open access: yesThe Astrophysical Journal Letters
Chemical 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 ...

Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d

open access: yesThe Astronomical Journal
LP 791-18 d is a temperate Earth-sized planet ( R _P = 1.03 R _⊕ , P = 2.76 days) orbiting a late M dwarf, with an interior super-Earth (LP 791-18 b, R _P = 1.2 R _⊕ , P = 0.95 days) and an exterior sub-Neptune (LP 791-18 c, R _P = 2.5 R _⊕ , P = 4.99 ...

The Formation of Double Hot Jupiter Systems through von Zeipel–Lidov–Kozai Migration

open access: yesThe Astrophysical Journal
The von Zeipel–Lidov–Kozai (ZLK) mechanism with tidal friction has been demonstrated as a promising avenue to generate hot Jupiters in stellar binary systems.

Planet–Planet Scattering and Von Zeipel–Lidov–Kozai Migration—The Dynamical History of HAT-P-11

open access: yesThe Astrophysical Journal
The two planets of the HAT-P-11 system represent fascinating dynamical puzzles due to their significant eccentricities and orbital misalignments. In particular, HAT-P-11 b is in a close-in orbit in which tides should have circularized well within the age

Tidal Evolution of Exoplanets

open access: yes, 2010
Tidal effects arise from differential and inelastic deformation of a planet by a perturbing body. The continuous action of tides modify the rotation of the planet together with its orbit until an equilibrium situation is reached.

Planetary Obliquity Excitation through Pre-main-sequence Stellar Evolution

open access: yesThe Astrophysical Journal
A planet’s axial tilt (“obliquity”) substantially affects its atmosphere and habitability. It is thus essential to comprehend the various mechanisms that can excite planetary obliquities, particularly at the primordial stage.
