Abstract
The authors discovered the eclipsing binary star system GSC 05765-01271 on August 19, 2015; here a preliminary model is presented. Lacking spectroscopic radial velocity data, period-based empirical relations have been used in order to constrain physical parameters as masses and radii. The effective temperature has been evaluated using color index (V–R) and spectral type estimated from a composite spectrum. These parameters were used as input to obtain a preliminary model of this binary system with Binary Maker 3 and PHOEBE software.
