Abstract

We present the orbital light curve and model system parameters of a newly discovered eclipsing binary star in the constellation of Perseus. Our professional-amateur astronomy collaboration between Arkansas Tech University (ATU), the Central Arkansas Astronomy Society (CAAS) and Whispering Pine Observatory, produced photometry in two wavelengths (Johnson V and R) in order to model the system for fundamental parameters with a binary modeling code. We determined that this binary system contains two F-type stars orbiting each other with a short orbital period and having the following characteristics for the two components: mass ratio (q ~ 0.92), temperatures (T1~ 7170 K, T2~ 7350 K), sizes (R1~ 1.7 R sun, R2~2.4 R sun), orbital inclination (i ~ 77o), and stellar separation (a ~ 8.3 R sun). The ephemeris for physical observations and primary mid-eclipse orbital phasing from the period in days is (HJD 2456488.885 + 1.292467 x N).
