The geometrical dimensions and radiative parameters of the component stars and the closed dinamic system of eclipsing binary stars can be calculated, in general, from the analysis of their light curves, which are express their light variability in time through their orbital period and constructed from their photometric observations. According to the basic aim of this project, new photometric observations of some selected W UMa type eclipsing binary stars which are mostly discoveries of the HIPPARCOS astrometry satellite and have no further information and light curve analysis in the literature, were obtained with the current telescopes of the Ankara University Observatory and TÜBİTAK National Observatory. The light curves constructed from these observations were analyzed for the first time. The eclipsing binary systems which are considered in this project have been selected among those systems that radial velocity curve analyses are present in the literature but, not the photometric orbital analyses. Therefore, their light curves were solved simultanously with their radial velocity curves. In that way, the absolute dimensions of the eclipsing binary systems considered in this project were obtained for the first time and their detailed nature are revealed. Contributing to the number of relevant eclipsing binary stars with well known radiative and geometrical parameters and providing some applicational data to various statistical generalizations and calibrations on them, we believe that, the findings and results of this project would take an great importance.
