Modeling Massive Stars with Rotation: the Case of Nitrogen Enrichments
A. Maeder, G. Meynet, S. Ekstrom +1
Recently, the concept of rotational mixing has been challenged by some authors (e.g. Hunter et al. 2008). We show that the excess N/H is a multivariate function f(M, age, v, sin i,…
The Gaia satellite: a tool for Emission Line Stars and Hot Stars
Christophe Martayan, Yves Fremat, Ronny Blomme +19
The Gaia satellite will be launched at the end of 2011. It will observe at least 1 billion stars, and among them several million emission line stars and hot stars. Gaia will provid…
Massive stars, globular clusters and elliptical galaxies
Georges Meynet, Thibaut Decressin, Corinne Charbonnel
Globular clusters as Cen and NGC 2808 appear to have a population of very He-rich stars. From a theoretical point of view, one expects the presence of He-rich stars in all glob…
Convective envelopes in rotating OB stars
André Maeder, Cyril Georgy, Georges Meynet
We study the effects of rotation on the outer convective zones of massive stars. We examine the effects of rotation on the thermal gradient and on the Solberg--Hoiland term by anal…
SPINSTARS at low metallicities
G. Meynet, S. Ekstrom, A. Maeder +3
The main effect of axial rotation on the evolution of massive PopIII stars is to trigger internal mixing processes which allow stars to produce significant amounts of primary nitro…
Can very massive stars avoid Pair-instability Supernovae?
S. Ekström, G. Meynet, A. Maeder
Very massive primordial stars () are supposed to end their lives as pair-instability supernovae. Such an event can be traced by a typical chemica…
