Neutron Stars in Globular Clusters"

In dense stellar systems, dynamical interactions between objects lead to the frequent formation of exotic stellar objects, unusual binaries and systems of higher multiplicity. This is particularly important for the question of formation of X-ray binaries. As only a very small fraction of the formed neutron stars is retained by globular clusters, this study inevitably becomes a million-body problem that demands the use of special numerical tools.

I will discuss how neutron stars are produced and retained ular clusters, outlining the most important dynamical channels and evolutionary events that affect the population of mass-transferring binaries with neutron stars and result in the formation of recycled pulsars. Other questions to be discussed are whether we can put constrains on the stellar evolution by comparing the observed millisecond pulsar population and theoretical results, as well as the nature of statistically significant overproduction of low-mass X-ray binaries in the metal-rich globular clusters.
