Spin-Orbital Evolution of Exoplanets [PDF]

EAS Publications Series, 2003
We investigated the equation describing the evolution of the kinetic momentum vector of planets by the action of gravitational and magnetic interaction. The obtained gallery of portraits of the kinetic momentum evolution illustrates the various regimes of planetary system evolution.

Evolution of Angular Momentum Distribution in Exoplanet Systems [PDF]

Astrophysics, 2015
The distribution of angular momentum is investigated in “star–planet systems, taking due account of stellar evolution effects. Numerical simulation is carried out for 15 systems for which stellar rotation data are available. Consideration of changes in stellar structure is confirmed to be significant for the evolution of momentum distribution.

Evolution of the obliquity of an exoplanet: A non-resonant case

Icarus, 2020
Abstract We investigate analytically and numerically the variation of the obliquity (the axial tilt) of a hypothetical exo-Earth. A large number of exoplanets was discovered recently; since not much information is available about the masses and orbits of the stars and planets comprising a planetary exo-system, unlike for the planets of the Solar ...

Rotational evolution of exoplanets under the action of gravitational and magnetic perturbations

Celestial Mechanics and Dynamical Astronomy, 2008
We investigate the evolution of the rotational axes of exoplanets under the action of gravitational and magnetic perturbations. The planet is assumed to be dynamically symmetrical and to be magnetised along its dynamical-symmetry axis. By qualitative methods of the bifurcation theory of multiparametric PDEs, we have derived a gallery of 69 phase ...

A radiogenic heating evolution model for cosmochemically Earth-like exoplanets

Icarus, 2014
Abstract Discoveries of rocky worlds around other stars have inspired diverse geophysical models of their plausible structures and tectonic regimes. Severe limitations of observable properties require many inexact assumptions about key geophysical characteristics of these planets.
