Helium diffusion during the evolution of solar-type stars : asteroseismic tests
arXiv:astro-ph/0510617
Abstract
The element diffusion, described by Michaud (1970), is now recognized to occur in all kinds of stars. We attempt to give evidence of signatures of helium diffusion below the convective zone by the way of asteroseismology.
