Scientific paper

The first detailed period study of the eclipsing RS CVn-binary system RW Com is presented. A new period (P = 0.2373455 d) based on 223 minima is given. The O-C diagrams of RW Com have been presented for the first time. Period changes in different portions of the O-C diagram have been estimated. The total change in period ranges from 5.5 x 10 to the -7th to 6.4 x 10 to the -6th. Numerous minima are available in the time interval 1967 to 1986. This part of the O-C diagram shows a sinusoidal variation; thus, it is suspected that RW Com could be a three-body system. The period of variation due to the third body appears to be nearly 16 years.
