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…

Properties of observable mixed inertial and gravito-inertial modes in γ Doradus stars
Marion Galoy, François Lignières, Jérôme Ballot
In γ Doradus stars, gravito-inertial modes in the radiative zone and inertial modes in the convective core can interact resonantly, which translates into the appearance of dip str…
