摘要

We present photometric and spectroscopic data of BN Ari,a totally eclipsing variable star.15 new times-of-minimum have been determined.These along with other published eclipse timings were used to update the linear ephemeris and evaluate changes in orbital periodicity.Radial velocity data along with a definitive classification spectrum are reported for the first time.Simultaneous modeling of multicolor light curves and radial velocity data was accomplished using the Wilson-Devinney code with optimization by differential corrections.The weight of evidence from evaluating both the eclipse timing differences and light curve modeling indicates that BN Ari is most likely a triple system.
