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…
Chemical composition of intermediate mass stars members of the M6 (NGC 6405) open cluster
Tolgahan Kılıçoğlu, Richard Monier, Jacques Richer +2
We present here the first abundance analysis of 44 late B, A and F-type members of the young open cluster M6 (NGC 6405, age about 75 Myrs). Spectra, covering the 4500 to 5800 Å wav…
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…
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…
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…
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…
