Abstract:
Detailed period study of the eclipsing binary system Delta Cap is presented. Available times of minima have been given. Period changes in different protions off the instant period trend. A new period of 1.ͩ0227789 has been given. Period changed in different portions of the O-C diagram have been estimated, which range from 6.4x10⁻⁶d to 1.8x10⁻³ d (?), the average being 3.5x10⁻⁵ d. A sinusoidal variation is evident in the O-C diagrams, which is indicative of the possible presence of a third body, having a period of nearly 62 years, however, it is yet to be confirmed.
