- W3048454229 abstract "The new ephemeris and light curve analysis by synthesizing our mid-eclipse times and the former observations of BF Pav, that is classified as a W UMa-type eclipsing binary, are presented in this study. We also obtain this binary system's period changes using the Wilson-Devinney code after eight nights of observation in BVRI filters from two observatories in Australia and Argentina. Our results demonstrate that BF Pav is a contact binary system with a photometric mass ratio q = 1.459 +- 0.020, a fillout factor f = 9.9%, and an inclination of 89.31+-0.49 deg which in the light curve solutions we have a cold spot. We also calculated the distance of BF Pav d = 243 +- 18 pc from the distance modulus formula, which is in good agreement with the distance obtained from this binary system's parallax in Gaia DR2. From our O-C analysis, we found a continuous period increase at a rate of 0.173277 . 10^(-7) days/year which corresponds to a period increase of 0.149 s century^(-1). We determined the mass of the primary component of this binary system using two different methods." @default.
