R. Spurzem et M. Giersz, A STOCHASTIC MONTE-CARLO APPROACH TO MODELING OF REAL STAR CLUSTER EVOLUTION .1. THE MODEL, Monthly Notices of the Royal Astronomical Society, 283(3), 1996, pp. 805-810
A new approach is outlined to follow the individual formation and evol
ution of hard three-body binaries in an evolving equal point mass star
cluster. The single stars are treated as a conducting gas sphere with
a standard anisotropic gaseous model, binary formation and subsequent
hardening by close encounters, and relaxation (dynamical friction) of
the binaries with the single stars by a Monte Carlo technique. The re
sults agree very well with the standard theoretical models and with a
direct N-body simulation. It is argued that the method can be extended
to generate an efficient, cheap and realistic model of large star clu
sters.
