Evolution of star clusters in arbitrary tidal fields
globular clusters: general – open clusters and associations: general – galaxies: star clusters – methods: analytical – methods: numerical
2011/10/20
We present a novel and flexible tensor approach to computing the effect of a time-dependent tidal field acting on a stellar system. The tidal forces are recovered from the tensor by polynomial interpo...
The Spitzer ice legacy: Ice evolution from cores to protostars
Spitzer ice legacy Ice evolution cores protostars
2011/10/20
Ices regulate much of the chemistry during star formation and account for up to 80% of the available oxygen and carbon. In this paper, we use the Spitzer c2d ice survey, complimented with data sets on...
Manganese evolution in Omega Centauri: a clue to the cluster formation mechanisms?
nuclear reactions nucleosynthesis abundances – galaxies: evolution – globular clusters: individual: ω Centauri
2011/10/18
We model the evolution of manganese relative to iron in the progenitor system of the globular cluster Omega Centauri by means of a self-consistent chemical evolution model. We use stellar yields that ...
Evolution of Super Star Cluster Winds with Strong Cooling
Evolution Super Star Cluster Winds Strong Cooling
2011/10/18
We study the evolution of Super Star Cluster (SSC) winds driven by stellar winds and supernova (SN) explosions. Time-dependent rates at which mass and energy are deposited into the cluster volume, as ...
