Magneto-Archeology of White Dwarfs. Revisiting the fossil field scenario with observational constraints during the red giant branch
Lukas Einramhof, Lisa Bugnet, Leila Magdalena Calcaferro +2
The detection of strong, large-scale magnetic fields at the surface of only the oldest population of white dwarfs might point towards a hidden internal magnetic field slowly rising…
The inertial dip as a window on the convective core dynamics
Lucas Barrault, Lisa Bugnet, Stéphane Mathis +1
Gamma Dor stars are ideal targets for studies of the innermost dynamical properties of stars, due to their rich frequency spectrum of gravito-inertial modes propagating in the radi…
Exploring the probing power of gamma-Dor's inertial dip for core magnetism: case of a toroidal field
Lucas Barrault, Lisa Bugnet, Stéphane Mathis +1
Gamma-Dor stars are ideal targets for studies of stellar innermost dynamical properties due to their rich asteroseismic spectrum of gravity modes. Integrating internal magnetism to…
Constraining differential rotation in gamma Doradus stars from inertial dips properties
L. Barrault, L. Bugnet, S. Mathis
The presence of dips in the gravity modes period spacing versus period diagram of gamma Doradus stars is now well established by recent asteroseismic studies. Such Lorentzian-shape…
Constraining core-to-envelope differential rotation in gamma-doradus stars from inertial dips properties
Lucas Barrault, Stéphane Mathis, Lisa Bugnet
The presence of dips in the gravito-inertial modes period-spacing pattern of gamma-Dor stars is now well established by recent asteroseismic studies. Such Lorentzian-shaped inertia…
