Massive star evolution at high metallicity
Georges Meynet, Nami Mowlavi, Andre Maeder
After a review of the many effects of metallicity on the evolution of rotating and non-rotating stars, we discuss the consequences of a high metallicity on massive star populations…
Evolution of the first stellar generations
R. Hirschi, A. Maeder, G. Meynet +2
Although the theoretical study of very low metallicity (Z) and metal-free stars is not new, their importance has recently greatly increased since two related fields have been devel…
CNO production in first generation stars
Sylvia Ekström, Georges Meynet, André Maeder
Big Bang nucleosynthesis produces only light elements and the very first generation stars are thus formed from metal-free clouds. They start the production of heavy elements during…
The Effective Temperatures and Physical Properties of Magellanic Cloud Red Supergiants: The Effects of Metallicity
Emily M. Levesque, Philip Massey, K. A. G. Olsen +3
We use the MARCS stellar atmosphere to derive the physical properties of 36 red supergiants (RSGs) in the LMC, and 39 RSGs in the SMC using moderate-resolution optical spectrophoto…
Evidence for rotation-induced mixing in evolved intermediate mass stars
R. Smiljanic, B. Barbuy, J. R. De Medeiros +1
Many observational results seem to indicate more efficient mixing processes in intermediate mass stars (5-20 M) than the expected by the standard models. These processes…
A strong case for fast stellar rotation at very low metallicities
C. Chiappini, R. Hirschi, G. Meynet +3
We investigate the effect of new stellar models, which take rotation into account, computed for a metallicity Z = 10^{-8} on the chemical evolution of the earliest phases of the Mi…
