Abstract

We present new multi-band differential aperture photometry of the eclipsing variable star NSVS 5750160. The light curves are analyzed with the Wilson-Devinney model to determine best-fit stellar models. Our models show that NSVS 5750160 is consistent with a W-type W Ursae Majoris eclipsing variable star, and require the presence of a spot to fit the observed O’Connell effect. Two different spot models are presented but neither model is conclusive.
