Observations of HZ Her in B and V Photometric Bands

Our ten-year B, V observations of the bright X-ray source Her X-1 (HZ Her) resulted in the determination of a new value for its precessional period, not exactly equal to 20.5 orbital periods. A previously unobserved phenomenon of rapid brightening of the accretion disk was also detected.

Abstract

Our ten-year B, V observations of the bright X-ray source Her X-1 (HZ Her) resulted in the determination of a new value for its precessional period, not exactly equal to 20.5 orbital periods. A previously unobserved phenomenon of rapid brightening of the accretion disk was also detected.
