Nonperiodic optical flickering in HZ Herculis

  • 1. The University of Texas at Austin and McDonald Observatory

Description

High-speed simultaneous dual-channel photometry of Hz Her and a nearby comparison star reveal nonperiodic optical flickering in the HZ Her system on a time scale of t5-300 s. The amplitude of the flickering appears to be correlated with orbital phase. Optical emission from a hot spot in a disk of material around the X-ray source cannot account for the flickering.
