Evidence for doppler-shifted iron emission lines in black hole candidate 4U 1630-47.
CUI W., CHEN W. and ZHANG S.N.
Abstract (from CDS):
The correlation between the lines implies a causal connection; perhaps they share a common origin. Both lines may arise from a single Kα line of highly ionized iron that is Doppler shifted either in a Keplerian accretion disk or in a bipolar outflow or even both. In both scenarios, a change in the line energy might simply reflect a change in the ionization state of line-emitting matter. We discuss the implication of the results and also raise some questions about such interpretations.
