An analytic model for blue straggler formation in globular clusters
Abstract
We present an analytic model for blue straggler formation in globular clusters. We assume that blue stragglers are formed only through stellar collisions and binary star evolution, and compare our predictions to observed blue straggler numbers. We can summarize our key results as follows. (1) Binary star evolution consistently dominates blue straggler production in all our best-fitting models. (2) In order to account for the observed sublinear …
