Nonlinear interaction between dynamo-generated magnetic fields, mean flows and internal gravity waves in stellar stably-stratified layers: From 3D to 1D
Florentin Daniel, Ludovic Petitdemange, Charly Pinçon +3
Magnetic fields have been constrained at the surface of several massive and intermediate-mass stars, but their origin and properties in deep stellar radiative interiors are still d…
Extra modes in helium-core-burning stars probing an infra core cavity
B. Mosser, M. Takata, C. Pinçon +5
Dipole mixed modes observed in the oscillation pattern of red giant stars probe the radiative regions in the stellar core. Oscillation spectra of helium-core-burning stars sometime…
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…
