Period variations in BZ Eridani

Abstract

The O-C diagram of BZ Eri has been presented for the first time, and the period variabtins present in the system have been analysed. In all, eight period decreases and eight period increases are noticed. Of these, four period decreases and seven period increases are appreciable. The strongest period changes are noticed in the interval 1960 to 1962. The total period changes in different portions of the O-C diagram ranges from 1.17 x 10⁻³ d to 3.96 x 10⁻⁶d. The trend of the period variation appears to have reversed around the year 1980.
