Photometry and analysis of the star HD 199 497
Two-color photoelectric observations of the new eclipsing binary HD 199497 are presented. These observations confirm that the system is a W UMatype eclipsing binary. The light curves were analyzed with theWilson-Devinney (1971) approach. The system is found to be in contactconfiguration. The inclination is amazingly small. Although there are nospectroscopic data, the photometric mass ratio of the system is welldetermined.
