Photometric Solutions of W UMa Type Stars: GSC2576-0319 and GSC2584-1731
High-precision photometric observations were performed in BVI bandpasses using 1m robotic telescope at Mt. Lemmon Observatory for two binary stars, which are reclassified as W UMa-type systems from ROTSE(Robotic Optical Transient Search Experiment) follow-up observations and show peculiar light vari...

| description |
High-precision photometric observations were performed in BVI bandpasses using 1m robotic telescope at Mt. Lemmon Observatory for two binary stars, which are reclassified as W UMa-type systems from ROTSE(Robotic Optical Transient Search Experiment) follow-up observations and show peculiar light variations. In order to analyze W UMa-type eclipsing binaries systematically, the light curve analysis script using 2005 version of Wilson-Devinney binary code is constructed. The orbital inclinations of GSC2584-1731 and GSC2576-0319 are 43.^circ5 and 57.^circ6 from light-curve analysis, respectively. Spot model is applied to explain the asymmetric light curve for GSC2584-1731 and the spot parameters are derived. |
