Abstract

The UBV photometry of a detached F-type eclipsing binary V505 Persei is presented. The light curve solution by a simple spherical model combined with the radial velocity data from two high resolution spectra by Marschall et al. (1990) reveals that the system is formed with two identical component stars of M approximate to 1.2M(-) in the main sequence close to ZAMS in evolution. They should have about solar metallicity (z approximate to 0.017). The isochrones with solar metallicity by Van denBerg (1985) yield an age of about (2.2 +/- 0.5) x 10(9) yr for the system. The distance of the system should be about 60 pc.
