Magnetohydrodynamic instabilities in stellar radiative regions. I. Linear study of shear-driven instabilities
V. Durepaire, L. Petitdemange, K. Belkacem +4
This paper is the first in a series investigating magnetohydrodynamic instabilities that may contribute to angular-momentum transport and magnetic-field evolution in stellar radiat…

Radial differential rotation leading to dipole collapse in pre-main-sequence stars
A. Guseva, L. Manchon, L. Petitdemange +1
Despite progress in the observations of stellar magnetic fields, their physical mechanisms remain poorly understood. During the pre-main sequence (PMS) phase, the inner layers of s…

Magnetic field morphologies in convective zones influenced by a turbulent surface layer
Anna Guseva, Ludovic Petitdemange, Charly Pinçon
Spectropolarimetric observations show that many low-mass stars possess large-scale poloidal magnetic fields with considerable dipole component, which in some cases exhibit temporal…
