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…
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…
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…
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…
