Hot horizontal branch stars in NGC 288 - effects of diffusion and stratification on their atmospheric parameters
S. Moehler, S. Dreizler, F. LeBlanc +5
NGC288 is a globular cluster with a well-developed blue horizontal branch covering the u-jump that indicates the onset of diffusion. It is therefore well suited to study the effect…
The stratified evolution of a cool star
G. Michaud, J. Richer, O. Richard
A low mass star usually experiences stratification and abundance anomalies during its evolution. A 0.95 solar mass star with a metallicity Z = 0.004 is followed from the main-seque…
Sirius A: turbulence or mass loss?
G. Michaud, J. Richer, M. Vick
Context. Abundance anomalies observed in a fraction of A and B stars of both Pop I and II are apparently related to internal particle transport. Aims. Using available constraints f…
Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss
M. Vick, G. Michaud, J. Richer +1
The effects of atomic diffusion on internal and surface abundances of A and F pre-main-sequence stars with mass loss are studied in order to determine at what age the effects mater…
CP and related phenomena in the context of Stellar Evolution
J. Braithwaite, T. Akgün, E. Alecian +13
We review the interaction in intermediate and high mass stars between their evolution and magnetic and chemical properties. We describe the theory of Ap-star `fossil' fields, befor…
