[40.01] A New Catalog of Contact Binary Stars from ROTSE-I Sky Patrols

S. J. Gettel, T. A. McKay, M. T. Geske (U. of Michigan)

Over 65,000 variable stars have been detected in the data from the ROTSE-I Sky Patrols. Using period-color and light curve selection techniques, about 5000 objects have been identified as contact binaries. This selection is tested for completeness against EW objects in the GCVS. By utilizing infrared color data from 2MASS, we fit a period-color-luminosity relation to these stars and estimate their distances.
