We present a detailed V-band photometric light curve modeling of 30 eclipsingbinaries using the data from Pietrukowicz et al. (2009) collected with theEuropean Southern Observatory Very Large Telescope (ESO VLT) of diameter 8-m.The light curve of these 30 eclipsing binaries were selected out of 148 of themavailable in the database on the basis of complete phase coverage, regular andsmooth phased light curve shapes. Eclipsing binaries play pivotal role in thedirect measurement of astronomical distances more accurately simply from theirgeometry of light curves. The accurate value of Hubble constant (H0) whichmeasures the rate of expansion of the Universe heavily relies on extragalacticdistance scale measurements. Classification of the selected binary stars in thesample were done, preliminarily on the basis of Fourier parameters in the a2-a4plane and final classification was obtained from the Roche lobe geometry. Outof these 30 eclipsing binaries, only one was found to be detached binary systemwhile the rest 29 of them belong to the contact binary systems. These contactbinaries were further classified into the A-type and W-type based on their massratios. Since spectroscopic mass ratio measurements were not available for anyof these binary stars, we determined the mass ratios through photometric lightcurve modeling with the aid of Wilson-Devinney code as implemented in PHOEBE.Various geometrical parameters and physical parameters of astrophysicalimportance viz., mass, radius and luminosity were obtained from the lightcurves of the selected stars.
