The basic role of magnetic field in stellar evolution
André Maeder, Georges Meynet, Cyril Georgy +1
Magnetic field is playing an important role at all stages of star evolution from star formation to the endpoints. The main effects are briefly reviewed. We also show that O-type st…
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 s process in massive stars at low metallicity. Effect of primary N14 from fast rotating stars
M. Pignatari, R. Gallino, G. Meynet +3
The goal of this paper is to analyze the impact of a primary neutron source on the s-process nucleosynthesis in massive stars at halo metallicity. Recent stellar models including r…
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…
Stellar Evolution in the Early Universe
R. Hirschi, U. Frischknecht, F. -K. Thielemann +5
Massive stars played a key role in the early evolution of the Universe. They formed with the first halos and started the re-ionisation. It is therefore very important to understand…
Wind anisotropy and stellar evolution
Cyril Georgy, Georges Meynet, André Maeder
Mass loss is a determinant factor which strongly affects the evolution and the fate of massive stars. At low metallicity, stars are supposed to rotate faster than at the solar one.…
