Abstract
We presented the physical properties of short period eclipsing binary systems by using the data obtained from Kepler Space Telescope. All the data were taken in wide band approaching to Johnson V filter. Since the spectroscopic data are not available, we used Wilson-Devinney code inside PHOEBE (v 0.031a) packages to determine the photometric mass ratio. We found the spectral types of the primary and secondary components of the binary systems from their effective temperatures according to the calibration of Morgan-Keenan (MK) (Drilling & Landolt 2002, Table 15.7). In our study we found two types of Eclipsing binaries W-UMa type and ELV type as they were obtained from the Roche Lobe geometry. Finally, we determined their absolute physical parameters by using different three methods (P. Harmanec (1988), Maceroni & Van{u2019}t Veer (1996), Gazeas & Niarchos (2006))
