Superhumps of CC Cancri Revisited
arXiv:astro-ph/0209322 · doi:10.1093/pasj/54.6.1017
Abstract
We observed the 2001 November superoutburst of CC Cnc. This observation makes the first detailed coverage of a superoutburst of this object. The best-determined mean superhump period is 0.075518 +/- 0.000018 d, which is 2.7% longer than the reported orbital period. This fractional superhump excess is a quite typical value for a normal SU UMa-type dwarf nova, excluding the previously raised possibility that CC Cnc may have an anomalously large fractional superhump excess. During the superoutburst plateau, the object showed a decrease of the superhump period at dot(P)/P = -10.2(1.3) x 10^(-5), which is one of the largest negative period derivative known in all SU UMa-type dwarf novae.
