Late superhumps and the stream-disc impact in IY UMa.

ROLFE D.J., HASWELL C.A. and PATTERSON J.

Abstract (from CDS):

We use the hotspot eclipse times of the newly discovered deeply eclipsing dwarf nova IY UMa to trace out the shape of its disc during the late superhump era. We find an eccentric disc. We show that the brightness of the stream-disc impact region varies as expected with |ΔV|2, where ΔV is the relative velocity of the stream with respect to the velocity of the disc at the impact point. We conclude that the hotspot is the source of late superhump light.
