The Gaia-ESO Survey: Evidence of atomic diffusion in M67?
C. Bertelli Motta, A. Pasquali, J. Richer +37
Investigating the chemical homogeneity of stars born from the same molecular cloud at virtually the same time is very important for our understanding of the chemical enrichment of…
Population II stars and the Spite plateau; Stellar evolution models with mass loss
Mathieu Vick, Georges Michaud, Jacques Richer +1
We aim to determine the constraints that observed chemical abundances put on the potential role of mass loss in metal poor dwarfs. Self-consistent stellar evolutionary models that…
Stellar Models with Enhanced Abundances of C, N, O, Ne, Na, Mg, Si, S, Ca, and Ti, in Turn, at Constant Helium and Iron Abundances
Don A. VandenBerg, Peter A. Bergbusch, Aaron Dotter +4
Recent work has shown that most globular clusters have at least two chemically distinct components, as well as cluster-to-cluster differences in the mean [O/Fe], [Mg/Fe], and [Si/F…
A search for magnetic fields in cool sdB stars
G. Mathys, S. Hubrig, E. Mason +3
Hot cluster Horizontal Branch (HB) stars and field subdwarf B (sdB) stars are core helium burning stars that exhibit abundance anomalies that are believed to be due to atomic diffu…
Horizontal Branch evolution, metallicity and sdB stars
G. Michaud, J. Richer, O. Richard
Context. Abundance anomalies have been observed in field sdB stars and in nearly all Horizontal Branch (HB) stars of globular clusters with Teff > 11 000K whatever be the cluster m…
AmFm and lithium gap stars: Stellar evolution models with mass loss
Mathieu Vick, Georges Michaud, Jacques Richer +1
A thorough study of the effects of mass loss on internal and surface abundances of A and F stars is carried out in order to constrain mass loss rates for these stars, as well as fu…
