Abstrakt
The available photometry from the online databases were used for the first light curve analysis of eight eclipsing binary systems El Aur, XY Dra, BP Dra, DD Her, VX Lac, WX Lib, RZ Lyn, and TV Tn. All these stars are of Algol-type, having the detached components and the orbital periods from 0.92 to 6.8 days.
For the systems El Aur and BP Dra the large amount of the third light was detected during the light curve solution. Moreover, 468 new times of minima for these binaries were derived, trying to identify the period variations.
For the systems XY Dra and VX Lac the third bodies were detected with the periods 17.7, and 49.3 years, respectively.
