Star formation in accretion discs : from the Galactic Center to Active Galactic Nuclei
Suzy Collin, Jean-Paul Zahn
Keplerian accretion discs around massive black holes (MBHs) are gravitationally unstable beyond a few hundredths of parsec and should collapse to form stars. Indeed an accretion/st…
On magnetic instabilities and dynamo action in stellar radiation zones
J. -P. Zahn, A. S. Brun, S. Mathis
We examine the MHD instabilities arising in the radiation zone of a differentially rotating star, in which a poloidal field of fossil origin is sheared into a toroidal field. We fo…
Advances in secular magnetohydrodynamics of stellar interiors dedicated to asteroseismic spatial missions
S. Mathis, P. Eggenberger, T. Decressin +5
With the first light of COROT, the preparation of KEPLER and the future helioseismology spatial projects such as GOLF-NG, a coherent picture of the evolution of rotating stars from…
