Abstract

We present two new eclipsing binary stars: HD 189735 (EB, P = 0.78154d) and HD 116274 (EW, P = 0.60471d). Light curves, periods, classifications, and Wilson-Devinney models are presented and discussed. Results for HD 189735 were originally presented at the Spring Meeting of the AAVSO in Tucson, Arizona in April of 2003
