The ages of Galactic globular clusters in the context of self-enrichment
T. Decressin, H. Baumgardt, P. Kroupa +2
A significant fraction of stars in globular clusters (about 70%-85%) exhibit peculiar chemical patterns with strong abundance variations in light elements along with constant abund…
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,…
Evolution and chemical and dynamical effects of high-mass stars
Georges Meynet, Cristina Chiappini, Cyril Georgy +4
We review general characteristics of massive stars, present the main observable constraints that stellar models should reproduce. We discuss the impact of massive star nucleosynthe…
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…
