The variable comparison stars in the field of the TeV blazar 1ES 1959+650
Abstract
We present the result of a study of two variable comparison stars in the field of the TeV blazar 1ES1959+650: star 5 (also known as the eclipsing binary MM Dra) and star 3 (currently of unknown type) from the comparison sequence of Villata et al. (1998). Thirteen years of data obtained with the three telescopes in WKU's telescope network (the 1.3m Robotically Controlled Telescope , the 0.6m Bell Observatory and the 1.3m AZT 11 at the Crimean Astrophysical Observatory) are analyzed and presented. Light curves created via differential photometry and phase diagrams are presented and discussed. We hope to resolve a discrepancy in the reported period of MM Dra and confirm/classify the variable nature of star 3.
