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…
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…
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…
Can very massive stars avoid Pair-Instability Supernovae?
Sylvia Ekström, Georges Meynet, André Maeder
Very massive primordial stars (140 Msol < M < 260 Msol) are supposed to end their lives as PISN. Such an event can be traced by a typical chemical signature in low metallicity star…
Physics of rotation in stellar models
Georges Meynet
In these lecture notes, we present the equations presently used in stellar interior models in order to compute the effects of axial rotation. We discuss the hypotheses made. We sug…
A new imprint of fast rotators: low 12C/13C ratios in extremely metal-poor halo stars
C. Chiappini, S. Ekström, G. Meynet +3
(abridged) Fast stellar rotation is currently the most promising mechanism for producing primary nitrogen in metal-poor massive stars. Chemical evolution models computed with the i…
