Massive stars: stellar models and stellar yields, impact on Galactic Archaeology
Georges Meynet, Arthur Choplin, Sylvia Ekstroem +1
The physics of massive stars depends (at least) on convection, mass loss by stellar winds, rotation, magnetic fields and multiplicity. We briefly discuss the impact of the first th…
Are some CEMP-s stars the daughters of spinstars?
Arthur Choplin, Raphael Hirschi, Georges Meynet +1
CEMP-s stars are long-lived low-mass stars with a very low iron content as well as overabundances of carbon and s-elements. Their peculiar chemical pattern is often explained by po…
Effects of axions on Population III stars
Arthur Choplin, Alain Coc, Georges Meynet +3
Following the renewed interest for axions as a dark matter component, we revisit the effects of energy loss by axion emission on the evolution of the first generation of stars. The…
Pre-supernova mixing in CEMP-no source stars
Arthur Choplin, Sylvia Ekström, Georges Meynet +3
Context. CEMP-no stars are long-lived low-mass stars with a very low iron content, overabundances of carbon and no or minor signs for the presence of s- or r-elements. Although the…
