| Abstract |
We present a direct N-body simulation modeling the evolution of the old
(7 Gyr) open cluster NGC 188. This is the first N-body open cluster
simulation whose initial binary population is directly defined by
observations of a specific open cluster: M35 (150 Myr). We compare the
simulated color-magnitude diagram at 7 Gyr to that of NGC 188, and
discuss the blue stragglers produced in the simulation. We compare the
solar-type main-sequence binary period and eccentricity distributions of
the simulation to detailed observations of similar binaries in NGC 188.
These results demonstrate the importance of detailed observations in
guiding N-body open cluster simulations. Finally, we discuss the
implications of a few discrepancies between the NGC 188 model and
observations and suggest a few methods for bringing N-body open cluster
simulations into better agreement with observations. |
