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,…

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.…

Massive star evolution: from the early to the present day Universe

Georges Meynet, Sylvia Ekstrom, Cyril Georgy +2

Mass loss and axial rotation are playing key roles in shaping the evolution of massive stars. They affect the tracks in the HR diagram, the lifetimes, the surface abundances, the h…

Developments in physics of massive stars

Georges Meynet, Sylvia Ekstrom, Andre Maeder +3

New constraints on stellar models are provided by large surveys of massive stars, interferometric observations and asteroseismology. After a review of the main results so far obtai…

Massive Stars as Cosmic Engines through the Ages

Andre Maeder, Georges Meynet, Sylvia Ekstrom +2

Some useful developments in the model physics are briefly presented, followed by model results on chemical enrichments and WR stars. We discuss the expected rotation velocities of…
