Data-driven discovery of dynamo cycle equations
Anna Guseva, Calum Skene, Steve Tobias
Many low-mass stars like the Sun host periodic, oscillatory magnetic fields that lead to variable levels of stellar activity, driving space weather that affects the habitability an…
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…
Coriolis darkening in late-type stars II. Effect of self-sustained magnetic fields in stratified convective envelope
C. Pinçon, L. Petitdemange, R. Raynaud +4
Modeling the surface brightness distribution of stars is of prime importance to interpret observations. Nevertheless, this remains quite challenging for cool stars as it requires o…
Data-driven scale identification in oscillatory dynamos
Anna Guseva
Parker's mean-field model includes two processes generating large-scale oscillatory dynamo waves: stretching of magnetic field lines by small-scale helical flows, and by differenti…
