Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou
L. Drouglazet, E. Alecian, A. Sousa +27
Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…
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…
Discovery of new magnetic δ Scuti stars and impact of magnetism on pulsation excitation
K. Thomson-Paressant, C. Neiner, J. Labadie-Bartz +3
Context. At this time, the list of known magnetic δ Scuti stars is extremely limited, with only a handful of well-studied examples. Aims. We seek to expand this list, by retrievin…
