Models for extremely metal-poor halo stars
A. Weiss, H. Schlattl, M. Salaris +2
Two alternative scenarios concerning the origin and evolution of extremely metal-poor halo stars are investigated. The first one assumes that the stars have been completely metal-f…

Atomic diffusion in metal poor stars. The influence on the Main Sequence fitting distance scale, subdwarfs ages and the value of Delta Y/DeltaZ
M. Salaris, M. A. T. Groenewegen, A. Weiss
The effect of atomic diffusion on the Main Sequence (MS) of metal-poor low mass stars is investigated. Since diffusion alters the stellar surface chemical abundances with respect t…

Chemical anomalies in globular cluster red giant stars and the "second parameter" problem
C. Charbonnel, P. A. Denissenkov, A. Weiss
We present the evolution of low mass and low metallicity RGB models computed under the assumption of deep mixing between the convective envelope and the hydrogen burning shell. We…
