Dynamical Evolution of Globular Clusters

Stephen McMillan (Drexel University, USA)
 

Globular clusters are among the most congested stellar systems in the universe.  Internal dynamical 
evolution drives them toward states of high central density, while simultaneously concentrating the most 
massive stars and binary systems in their cores.  As a result, these clusters are expected to be sites of 
frequent close encounters and physical collisions between stars and binaries, making them extraordinarily 
efficient factories for the production of interesting and eminently observable astrophysical exotica. I will 
describe some elements of the competition among stellar dynamics, stellar evolution, and other processes 
that control globular cluster dynamics, with particular emphasis on pathways that may lead to the formation 
of blue straggler stars.
