[71.02] WIYN Open Cluster Study: A Search for Variability in NGC 2141

J. Kissinger (Florida Institute of Technology, Indiana University), S. Kafka (Cerro Tololo Inter-American Observatory)

We present the results of a variability study of the old (2.5+/- ???) open cluster NGC 2141 as a part of the WIYN Open Cluster Study (WOCS). Our data were collected using an R filter with S2KB on the WIYN 0.9 meter telescope during January and March of 2005. A total of 49 candidate variables were discovered in the vicinity of the cluster. Seven of those are of W UMa type, with periods ranging from 0.228 to 0.328 hours. Twelve other systems are eclipsing binaries, while the rest can not be identified with the data in hand. Using additional V and B images, we also constructed a color magnitude diagram of the cluster, verifying the presence of differential reddening across the field of the cluster.
