CC Sculptoris: A superhumping intermediate polar

Show Summary Details


We present high-speed optical, spectroscopic and Swift X-ray observations made during the dwarf nova superoutburst of CC Scl in 2011 November. An orbital period of 1.383 h and superhump period of 1.443 h were measured, but the principal new finding is that CC Scl is a previously unrecognized intermediate polar, with a white dwarf spin period of 389.49 s which is seen in both optical and Swift X-ray light curves only during the outburst. In this it closely resembles the old nova GK Per, but unlike the latter has one of the shortest orbital periods among intermediate polars.
