Evolution of spiral shocks in U Geminorum during outburst.

GROOT P.J.

Abstract (from CDS):

Time-resolved spectroscopic observations of U Geminorum during its 2000 March outburst show strong spiral shocks in the accretion disk. During the plateau at maximum brightness, the spiral shocks contribute ∼14% to the total He II flux. The two arms of the spiral show a distinctly different evolution during the outburst and decline, which indicates an asymmetric evolution in the disk.
