dc.description.abstractThe first BVR photometry and light curve modeling of totally eclipsing detached binary V667 Lyr are presented. Eclipse timings obtained in this study were used to determined accurate light elements of the system. Eclipse depth of light curves indicates similar to 1500 K temperature difference while relatively long total eclipse shows large radius difference between components. Advantage of total eclipse allowed to estimate mass ratio of the system via well known mass-luminosity relation as q = 0.54. Analysis showed that the secondary component has sub-solar mass, which brings to mind chromospheric activity possibility. However, no remarkable asymmetries in light and color curves were observed in the first observations. By using photometric properties, mass ratio and period of the system, masses and radii of the primary and secondary components were estimated as M-1 = 1.55 M-circle dot, M-2 = 0.84 M-circle dot and R-1 = 1.98 R-circle dot, R-2 = 0.95 R-circle dot, respectively. Estimated physical properties of the primary component put the system on a distance of 680 pc. (C) 2013 Elsevier B.V. All rights reserved.en_US
