X-Ray Absorption in CIRCINUS-X-1 in the Low State
Abstract
We report observations of Cir X-1 with the Ariel 5 spectrometer, showing that the hydrogen column density in the low state is comparable to that observed in the high state. The implications of this fact for the models of the source are discussed.
