Dynamical mixing of two stellar populations in globular clusters
T. Decressin, H. Baumgardt, P. Kroupa
Stars in globular clusters (GCs) exhibit a peculiar chemical pattern with strong abundance variations in light elements along with a constant abundance in heavy elements. These abu…
The evolution of two stellar populations in globular clusters I. The dynamical mixing timescale
T. Decressin, H. Baumgardt, P. Kroupa
We investigate the long-term dynamical evolution of two distinct stellar populations of low-mass stars in globular clusters in order to study whether the energy equipartition proce…
Origin of the abundance patterns in Galactic globular clusters: constraints on dynamical and chemical properties of globular clusters
T. Decressin, C. Charbonnel, G. Meynet
Aims. We analyse the effects of a first generation of fast rotating massive stars on the dynamical and chemical properties of globular clusters. Methods. We use stellar models of f…
Fast rotating massive stars and the origin of the abundance patterns in galactic globular clusters
T. Decressin, G. Meynet, C. Charbonnel +2
We propose the Wind of Fast Rotating Massive Stars scenario to explain the origin of the abundance anomalies observed in globular clusters. We compute and present models of fast ro…
