A Study of the Orbital Periods of 22 Eclipsing Binaries
Investigation of the variability of the orbital periods of eclipsing binaries is important not only from the evolutionary point of view but also for detecting additional components in them. Systematic study of the period changes in binary stars was started by Plavec (Plavec et al 1960) more than twenty years ago. Work on the same lines for 20 detached systems was reported by Herczeg (1980) at the I.A.U. Symposium No. 88 held in Toronto two years ago. Here we describe the study of 22 systems carried out by us at Hyderabad.
