Multi-filter Photometric Analysis of W Ursae Majoris (W UMa) Type Eclipsing Binary Stars KID 11405559 and V342 Boo
We present light curve analysis of two variable stars, KID 11405559 and V342 Boo. KID 11405559 is selected from the Kepler Eclipsing Binary Catalog published by Kirk et al. (2016) and V342 Boo from a list of eclipsing binaries published by Kreiner (2004). In this paper, we present the light curves for these two objects using data collected at the 31-inch NURO telescope at Lowell Observatory in Flagstaff, Arizona, in three filters: Bessell B, V, and R. We generate truncated twelve-term Fourier fits for the light curves and quantify the O'Connell effect exhibited by these systems by calculating the difference Delta I in the heights of the primary and secondary maxima: the "Light Curve Asymmetry" (LCA) and the "O'Connell Effect Ratio" (OER). Additionally, we use the Fourier coefficients from the Fourier fit to confirm that KID 11405559 and V342 Boo are W UMa type eclipsing binary stars.
