CoRoT measures solar-like oscillations and granulation in stars hotter than the Sun
E. Michel, A. Baglin, M. Auvergne +2
Oscillations of the Sun have been used to understand its interior structure. The extension of similar studies to more distant stars has raised many difficulties despite the strong…
The seismology programme of CoRoT
E. Michel, A. Baglin, M. Auvergne +1
We introduce the main lines and specificities of the CoRoT Seismology Core Programme. The development and consolidation of this programme has been made in the framework of the CoRo…
Modelling element distributions in the atmospheres of magnetic Ap stars
G. Alecian, M. J. Stift
In recent papers convincing evidence has been presented for chemical stratification in Ap star atmospheres, and surface abundance maps have been shown to correlate with the magneti…
Scandium: A key element for understanding Am stars
F. LeBlanc, G. Alecian
{\rm Context.} Atomic diffusion is believed to cause the abundance anomalies observed in AmFm stars. However, the detailed process has still not been well-established. For instance…
Radiative diffusion in stellar atmospheres: diffusion velocities
G. Alecian, M. J. Stift
The present paper addresses some of the problems in the buildup of element stratification in stellar magnetic atmospheres due to microscopic diffusion, in particular the redistribu…
Time-dependent diffusion in A-stars
Georges Alecian
Each time diffusion of elements is invoked in explaining abundance anomalies in a star, this supposes implicitly that a stratification process is in progress somewhere in that star…
