Boron depletion in 9 to 15 M(circle dot) stars with rotation
Frischknecht, U.; Hirschi, R.; Meynet, G.; Ekstroem, S.; Georgy, C.; Rauscher, T.; Winteler, C.; Thielemann, F-K. (Cambridge University Press, 2010)The treatment of mixing is still one of the major uncertainties in stellar evolution models. One open question is how well the prescriptions for rotational mixing describe the real effects. We tested the mixing prescriptions ... -
Constraints on rotational mixing from surface evolution of light elements in massive stars
Frischknecht, U.; Hirschi, R.; Meynet, G.; Ekstroem, S.; Georgy, C.; Rauscher, T.; Winteler, C.; Thielemann, Friedrich-Karl (2010-11)Context. Light elements and nitrogen surface abundances together can constrain the mixing efficiencies in massive stars on the main sequence, because moderate mixing in the surface layers leads to depletion of light elements ... -
Superbubble dynamics in globular cluster infancy. I. How do globular clusters first lose their cold gas?
Krause, M.; Charbonnel, C.; Decressin, T.; Meynet, G.; Prantzos, N.; Diehl, R. (2012-10-05)The picture of the early evolution of globular clusters has been significantly revised in recent years. Current scenarios require at least two generations of stars of which the first generation (1G), and therefore also the ... -
Superbubble dynamics in globular cluster infancy. II. Consequences for secondary star formation in the context of self-enrichment via fast-rotating massive stars
Krause, M.; Charbonnel, C.; Decressin, T.; Meynet, G.; Prantzos, N. (2013-04-12)Context. The self-enrichment scenario for globular clusters (GC) requires large amounts of residual gas after the initial formation of the first stellar generation. Recently, we found that supernovae may not be able to ...
