Circinus X-1: A Laboratory for Studying the Accretion Phenomenon in Compact Binary X-Ray Sources

摘要

Observations of the binary X-ray source Circinus X-1 provide samples of a range of spectral and temporal behavior whose variety is thought to reflect a broad continuum of accretion conditions in an eccentric binary system. The data support an identification of three or more X-ray spectral components, probably associated with distinct emission regions.
