Perturbative analysis of the effect of a magnetic field on gravito-inertial modes
François Lignières, Jérôme Ballot, Sébastien Deheuvels +1
Magnetic fields have been measured recently in the core of red giant stars thanks to their effects on stellar oscillation frequencies. The search for magnetic signatures in pulsati…
Internal magnetic fields in 13 red giants detected by asteroseismology
Gang Li, Sébastien Deheuvels, Tanda Li +2
While surface fields have been measured for stars across the HR diagram, internal magnetic fields remain largely unknown. The recent seismic detection of magnetic fields in the cor…
Impact of central mixing scheme and nuclear reaction network on the extent of convective cores
Anthony Noll, Sébastien Deheuvels
Convective cores are the hydrogen reservoirs of main sequence stars that are more massive than around 1.2 solar masses. The characteristics of the cores have a strong impact on the…
Strong magnetic fields detected in the cores of 11 red giant stars using gravity-mode period spacings
S. Deheuvels, G. Li, J. Ballot +1
Despite their importance in stellar evolution, little is known about magnetic fields in the interior of stars. The recent seismic detection of magnetic fields in the core of severa…
