Atomic diffusion in star models of type earlier than G | | P. Morel

24 May 2002 | | Subject: | astro-ph | | Affiliation: | Departement Cassini, Observatoire de la Cote d’Azur, Nice, France. | | Abstract: | We find that the radiative diffusivity associated with the radiative viscosity generates a mixing that diminishes the efficiency of the gravitational settling in the external layers of stellar models corresponding to types earlier than G. The surface abundances of chemical species predicted by the models are successfully compared with the abundances determined in members of the Hyades open cluster. Our modeling depends on an efficiency parameter, which is evaluated to a value close to unity, that we calibrate in this study. | | Source: | arXiv, astro-ph/0205434 | | Services: | Forum | Review | PDF | Favorites | |
