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…
Nucleosynthesis in the first massive stars
Arthur Choplin, Georges Meynet, Andre Maeder +2
The nucleosynthesis in the first massive stars may be constrained by observing the surface composition of long-lived very iron-poor stars born around 10 billion years ago from mate…
