Abstract

Investigation of changes in the light of a binary star with plotted light curves, which shows the variation of light during a periodic time, helps us to obtain useful information about the binary systems. In this article, by R-band photometric light curve modeling of BN Ari binary star (in 2015) which is located in Aries constellation, we plot related light curve, obtain new period for the system and calculate the rate of period changes. We also calculate a new ephemeris of such system by fitting a quadratic curve to the OC values. Finally, we use the Wilson–Devinney code as implemented in the PHOEBE to simulate such a system, and obtain its specific geometrical and physical parameters.
