Magnetic and tidal interactions in spin evolution of exoplanets [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractThe axis-rotational evolution of exoplanets on close orbits strongly depends on their magnetic and tidal interactions with the parent stars. Impulsive perturbations from a star created by periodical activity may accumulate with time and lead to significant long-term perturbations of the planet spin evolution.

Magnetic Field Evolution of Hot Exoplanets

Monthly Notices of the Royal Astronomical Society
ABSTRACT Numerical simulations have shown that the strength of planetary magnetic fields depends on the convective energy flux emerging from planetary interiors. Here, we model the interior structure of gas giant planets using mesa, to determine the convective energy flux that can drive the generation of magnetic field. This flux is then

The Possible Evolution of an Exoplanet’s Atmosphere

Eos, 2021
Scientific sleuths explore data gathered trillions of kilometers away and put forth different, and often conflicting, ideas to reconstruct the gaseous envelope on a distant rocky exoplanet, GJ 1132 b.

Tidal evolution of close-in exoplanets in co-orbital configurations [PDF]

Celestial Mechanics and Dynamical Astronomy, 2013
In this paper, we study the behavior of a pair of co-orbital planets, both orbiting a central star on the same plane and undergoing tidal interactions. Our goal is to investigate final orbital configurations of the planets, initially involved in the 1/1 mean-motion resonance (MMR), after long-lasting tidal evolution.

Theoretical models of planetary system formation. II. Post-formation evolution [PDF]

, 2015
We extend the results of planetary formation synthesis by computing the long-term evolution of synthetic systems from the clearing of the gas disk into the dynamical evolution phase.

Exoplanet status report: Observation, characterization and evolution of exoplanets and their host stars

Solar System Research, 2010
After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science during the past decade. The characterization of exoplanets can only be carried out in a well coordinated interdisciplinary way which connects ...

Tidal Evolution of Exoplanets

, 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. It is often believed that synchronous motion is the most probable outcome of the tidal evolution process, since synchronous ...
