Young Massive Star Clusters
Young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they
Binary Interaction Dominates the Evolution of Massive Stars
More than 70% of all massive stars will exchange mass with a companion, leading to a binary merger in one-third of the cases, greatly exceed previous estimates and imply that binary interaction dominates the evolution of massive stars, with implications for populations ofmassive stars and their supernovae.
An analytical description of the disruption of star clusters in tidal fields with an application to Galactic open clusters
We present a simple analytical description of the disruption of star clusters in a tidal field. The cluster disruption time, defined as tdis = {dln M/dt} −1 , depends on the mass M of the cluster as
The luminosity function of young star clusters: implications for the maximum mass and luminosity of clusters.
We introduce a method to relate a possible truncation of the star cluster mass function at the high mass end to the shape of the cluster luminosity function (LF). We compare the observed LFs of five
Hierarchical Star Formation in M51: Star/Cluster Complexes
We report on a study of young star cluster complexes in the spiral galaxy M51. Recent studies have confirmed that star clusters do not form in isolation, but instead tend to form in larger groupings
Disruption time scales of star clusters in different galaxies
The observed average lifetime of the population of star clusters in the Solar Neighbourhood, the Small Magellanic Cloud and in selected regions of M 51 and M 33 is compared with simple theoretical
The VLT-FLAMES Tarantula Survey. VIII. Multiplicity properties of the O-type star population
Context. The Tarantula Nebula in the Large Magellanic Cloud is our closest view of a starburst region and is the ideal environment to investigate important questions regarding the formation,
Lifetimes of tidally limited star clusters with different radii
We study the escape rate of stars, (N)over dot, from clusters with different radii on circular orbits in a tidal field using analytical predictions and direct N-body simulations. We find that (N)over
Star cluster disruption by giant molecular clouds
We investigate encounters between giant molecular clouds (GMCs) and star clusters. We propose a single expression for the energy gain of a cluster due to an encounter with a GMC, valid for all
Evidence for two populations of Galactic globular clusters from the ratio of their half-mass to Jacobi radii
We investigate the ratio between the half-mass radii r(h) of Galactic globular clusters and their Jacobi radii r(J) given by the potential of the Milky Way and show that clusters with galactocentric
