Seismic detection of core magnetic fields in red giants using the gravity offset
Matisse Villate, Sébastien Deheuvels, Jérôme Ballot
Magnetic fields are known to efficiently redistribute angular momentum in stars. They have been recently measured in the cores of red giant stars using asteroseismology. It was sho…
Is a 1D perturbative method sufficient for asteroseismic modelling of Cephei pulsators? Implications for measurements of rotation and internal magnetic fields
J. S. G. Mombarg, V. Vanlaer, S. B. Das +6
Asymmetries in the observed rotational splittings of a multiplet contain information about the star's rotation profile and internal magnetic field. However, to exploit this informa…
Automated detection of exploding granules with SDO/HMI data
J. Ballot, T. Roudier
Exploding granules on the solar surface play a major role in the dynamics of the outer part of the convection zone, especially in the diffusion of the magnetic field. We aim to dev…
About the p-mode frequency shifts in HD 49933
D. Salabert, C. Regulo, J. Ballot +2
We study the frequency dependence of the frequency shifts of the low-degree p modes measured in the F5V star HD 49933, by analyzing the second run of observations collected by the…
