Abstract

The old open cluster NGC 188 is unique because of its large number of W UMa type contact binaries. This allows astronomers to use these stars to refine models of the origin and evolution of these systems. Also because of its age, NGC 188 may display a wide range of contact binary systems, from the W UMa binaries to the highly evolved FK Comae type star in which the two stellar cores have coalesced. It was our goal to find and classify new variable stars in this cluster.
