Planetary migration: magnetic or tidal effects ?
A large part of the exoplanets known today are in very close orbit around their star, allowing very intense interactions between the planets and the host star.

The secret of the star magnetic cycles
Thanks to new numerical simulations, a scientific team led by researchers from the Astrophysics Department-Laboratory AIM of CEA-Irfu has succeeded in explaining why the magnetic field of the Sun reverses every 11 years.

The evolution of the structure and the rotation of the central star drastically modify the orbits of the planets
In a special issue of the international journal Celestial Mechanics and Dynamical Astronomy of November 2016, devoted to the study of the tidal interactions, two researchers from the University of Namur and the Astrophysics Division- AIM Laboratory of CEA-Irfu have computed the dynamics of short-period planets of different types orbiting low-mass mass stars.
