Magnetic interactions between close-in planets and their host star can play an important role
in the secular orbital evolution of the planets, as well as the rotational evolution of their host. …

Magnetic interactions between a star and a close-in planet are postulated to be a source of
enhanced emissions and to play a role in the secular evolution of the orbital system. Close-in …

This paper addresses non-linear gyrokinetic simulations of ion temperature gradient (ITG)
turbulence in tokamak plasmas. The electrostatic GYSELA code is one of the few international …

Stellar wind is thought to be the main process responsible for the spin down of main-sequence
stars. The extraction of angular momentum by a magnetized wind has been studied for …

Shortly after the seminal paper “Self-Organized Criticality: An explanation of 1/f noise” by
Bak et al. ( 1987 ), the idea has been applied to solar physics, in “Avalanches and the …

The turbulent transport governed by the toroidal ion temperature gradient driven instability
is analysed with the full-f global gyrokinetic code GYSELA (Grandgirard et al 2007 Plasma …

Exoplanets on close-in orbit are subject to intense interactions with their host star. They
receive a strong irradiation from the star, trigger tides within their host, and stars and close-in …

We use the anelastic spherical harmonic code to model the convective dynamo of solar-type
stars. Based on a series of 15 3D MHD simulations spanning four bins in rotation and mass, …

We present a spectroscopic analysis of a 1-yr intensive monitoring campaign of the 22-Myr
old planet-hosting M dwarf AU Mic using the HARPS spectrograph. In a companion paper, …
