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

open access: closed
Studying network of symmetric periodic orbit families of the Hill problem via symplectic invariants In the framework of the spatial circular Hill three-body problem we illustrate the application of symplectic invariants to analyze the network structure of symmetric periodic orbits families.

Orbital precession in short-period hot jupiter exoplanet systems

Monthly notices of the Royal Astronomical Society, 2023
In several exoplanet systems the stellar rotation axis is not aligned with the normal to the orbital plane. For the class of ‘hot Jupiters’, a significant fraction of total angular momentum resides in the orbit.

Tides and angular momentum redistribution inside low-mass stars hosting planets: a first dynamical model

Celestial mechanics & dynamical astronomy, 2016
We introduce a general mathematical framework to model the internal transport of angular momentum in a star hosting a close-in planetary/stellar companion. By assuming that the tidal and rotational distortions are small and that the deposit/extraction of

From Tides to Currents: Unraveling the Mechanism that Powers WASP-107b’s Internal Heat Flux

Astrophysical Journal
The sub-Jovian exoplanet WASP-107b ranks among the best-characterized low-density worlds, featuring a Jupiter-like radius and a mass that lies firmly in the sub-Saturn range.

Planetary orbital equations in externally-perturbed systems: position and velocity-dependent forces

Celestial mechanics & dynamical astronomy, 2012
The increasing number and variety of extrasolar planets illustrates the importance of characterizing planetary perturbations. Planetary orbits are typically described by physically intuitive orbital elements.

Tidal Synchronization of TESS Eclipsing Binaries

Astrophysical Journal
Tidal synchronization plays a fundamental role in the evolution of binary star systems. However, key details such as the timescale of synchronization, efficiency of tidal dissipation, rotation period, and dependence on stellar mass are not well ...

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

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
