NICER observation list: Target ID 765601

A rare class of CVs harbors rapidly rotating white dwarfs (WDs), with spin periods as fast as ~30 seconds, due to substantial spin-up in their evolution paths. These fast-spinning CVs (FSCVs), currently spinning down, display unique characteristics such as WD pulsars and propeller systems. We propose to measure the spin derivative of the second-fastest spinning WD discovered in an intermediate polar (IP) called CTCV J2056-3014, and determine whether the WD is spinning down as other FSCVs or up as regular IPs. The WD spin rate is a key parameter to constrain the WD B-field, mass and spin evolution. We also request a NICER ToO to characterize the X-ray evolution of this unique FSCV during the next superoutburst, a rare outburst caused by tidal-thermal instabilities in the accretion disk.
