Tides on Other Earths: Implications for Exoplanet and Palaeo-Tidal Simulations [PDF]

Geophysical Research Letters, 2020
AbstractA key controller of a planet's rotational evolution, and hence habitability, is tidal dissipation, which on Earth is dominated by the ocean tides. Because exoplanet or deep‐time Earth topographies are unknown, a statistical ensemble is used to constrain possible tidal dissipation rates on an Earth‐like planet.

An Apparently Eccentric Orbit of the Exoplanet WASP-12 b as a Radial Velocity Signature of Planetary-Induced Tides in the Host Star [PDF]

Astrophysical Journal, 2020
Abstract Massive exoplanets on extremely tight orbits, such as WASP-12 b, induce equilibrium tides in their host stars. Following the orbital motion of the planet, the tidal fluid flow in the star can be detected with the radial velocity method.

Frontiers of exoplanet dynamics with JWST: Tides, rotation, rings, moons, and more

JWST can probe the orbital and physical properties of exoplanets in greater detail than ever before, thanks to its superior light gathering power and measurement precision. Not only does JWST allow for improvement in existing dynamical techniques such as transit-timing variations; it also has the potential to unveil phenomena that were previously ...

Atmospheric Thermal Tides of Exoplanets

Gravitational interactions between a planet and its host star may have important effects on the orbit and rotation rates of the two bodies. Gravitational tides, through tidal friction, change the rotation period of a planet, ultimately synchronizing it with its orbital period and tidally locking it when the orbit is nearly circular. While the theory of

Studying network of symmetric periodic orbit families of the Hill problem via symplectic invariants, Extension of the creep tide theory to exoplanet systems with high stellar obliquity

This seminar presents two distinct advances in celestial mechanics and exoplanetary dynamics. The first study investigates the network of symmetric periodic orbit families in the Hill problem, a fundamental model in celestial mechanics describing the motion near a small body perturbed by a larger primary. By employing symplectic invariants—specifically

Effects of tides on the infrared light curve of rocky exoplanets

2011
Short-period exoplanets undergo strong tidal interactions that affect their orbital and spin evolution and their internal structure via tidal heating. Tidal models are, however, limited by uncertainties on key processes such as the dissipation rate. We show here that infrared photometric monitoring of eccentric rocky exoplanets can be used to determine
