An analytic technique for constraining the dynamical origins of multiple star systems containing merger products.
LEIGH N. and SILLS A.
Abstract (from CDS):
We have applied our analytic prescription to observed binary and triple systems containing blue stragglers (BSs), in particular the triple system S1082 in M67, and the period distribution of the BS binaries in NGC 188. We have shown that both S1082 and most of the BS binaries in NGC 188 could have a dynamical origin and that encounters involving triples could be a significant contributor to BS populations in old open clusters. In general, our results suggest that encounters involving triples could make up a significant fraction of those dynamical interactions that result in stellar mergers, in particular, encounters that produce multiple star systems containing one or more BSs.
