Abstract

Presented are a set of multi-band light curves, synthetic light curve solutions, and period study for the eclipsing binary star BN Ari. The orbital period was found to be decreasing the past 8 years (~8,200 orbits). The observed light curves were analyzed with the Wilson-Devinney program. The resulting synthetic light curve solution showed the system to be a contact eclipsing binary with total eclipses.
