Analysis of the light curves of the eclipsing system V548 Cygni

The eclipsing binary V548 Cygni was observed photoelectrically in yellow and blue light at Ege University Observatory in 1975. A total of 857 observations were obtained of each colour. Three times of minima were obtained and new light elements were derived. The orbital analysis were made by the methods of Kitamura and Wood. The system has a third body whose total luminosity is greater than that of secondary companion. © 1981 D. Reidel Publishing Company
