Abstract

We present new multi-band differential aperture photometry of the eclipsing variable star ASAS J184708-3340.2. The light curves are analyzed with the Wilson-Devinney model to determine best-fit stellar models. Our models show that ASAS J184708-3340.2 is consistent with an overcontact eclipsing binary (W Ursae Majoris) system with total eclipses.
