Seismic signature of a magnetic field in the Doradus star KIC 2309579

S. Ihallaine, J. Ballot, F. Lignières +4

Internal magnetic fields have recently been detected and measured in the radiative core of red giant stars using asteroseismology. Being one of red giant stars progenitors and exhi…

Near-critical magnetic fields in Kepler red giants

S. Deheuvels, J. Ballot, F. Lignières +2

The recent seismic detection of magnetic fields in red giants cores has given the opportunity to characterize these fields, potentially giving information about their origin and th…

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…

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…

A decade-long magnetic monitoring of Vega

P. Petit, T. Böhm, C. P. Folsom +2

Aims. The very weak magnetic field detected at the surface of Vega hints at a widespread population of weakly magnetic stars of A and B spectral types. We contribute here to gather…
