Evidence for a relativistic iron line in GRS 1915+105.

MARTOCCHIA A., MATT G., KARAS V., BELLONI T. and FEROCI M.

Abstract (from CDS):

We report on the discovery of a relativistic iron Kα fluorescent emission line in the BeppoSAX spectrum of the microquasar GRS 1915+105, taken on April 19, 1998, when the line was unusually intense. The feature is broad and skewed, clearly indicating emission from the innermost regions of the accretion disc. The inner emitting orbit is larger than the innermost stable orbit, even in Schwarzschild metric: thus, a non-zero BH spin is not required by these data.
