Star cluster ecology IVa: Dissection of an open star cluster—photometry
The evolution of star clusters is studied using N-body simulations in which the evolution of single stars and binaries are taken self-consistently into account. Initial conditions are chosen to represent relatively young Galactic open clusters, such as the Pleiades, Praesepe and the Hyades. The calculations include a realistic mass function, primordial binaries and the external potential of the...
متن کاملStar cluster ecology II. Binary evolution with single-star encounters
Three-body effects greatly complicate stellar evolution. We model the effects of encounters of binaries with single stars, based on parameters chosen from conditions prevalent in the cores of globular clusters. For our three-body encounters, we start with a population of primordial binaries, and choose incoming stars from the evolving single star populations of paper I. In addition, we study th...
متن کاملNew stellar members of the Coma Berenices open star cluster
We present the results of a survey of the Coma Berenices open star cluster (Melotte 111), undertaken using proper motions from the USNO-B1.0 and photometry from the 2MASS Point Source catalogues. We have identified 60 new candidate members with masses in the range 1.007M⊙<M<0.269M⊙. For each we have estimated a membership probability by extracting control clusters from the proper motion vector ...
متن کاملStar Cluster Survey . III . The White Dwarf Cooling Age of the Rich Open Star Cluster NGC 2099 ( M 37 )
We present deep CCD photometry of the very rich, intermediate aged (similar to the Hyades) open star cluster NGC 2099 (M37). The V, B−V color-magnitude diagram (CMD) for the cluster shows an extremely well populated and very tightly constrained main-sequence extending over 12 magnitudes from the turn-off. Both a well defined main-sequence turn-off and a red giant population are also clearly evi...
متن کاملAn XMM–Newton view of the young open cluster NGC 6231 – II. The OB star population
In this second paper of the series, we pursue the analysis of the 180-ks XMM–Newton campaign towards the young open cluster NGC 6231 and we focus on its rich OB star population. We present a literature-based census of the OB stars in the field of view with more than one hundred objects, among which 30 per cent can be associated with an X-ray source. All the O-type stars are detected in the X-ra...
