NICER observation list: Target ID 459201

Abstract

A recently-discovered intermediate polar, CTCV J2056-3014, has the shortest spin period (29.6 sec) among all CVs and white dwarfs. The orbital period of 1.76 hours is below the period gap where the binary orbit decays via gravitational wave radiation. Fast-spinning CVs are extremely rare and unique as manifested by AR Sco (the so-called white dwarf pulsar) and AE Aqr which spins down via the propeller effect. The proposed NICER and NuSTAR observations, motivated by the recent XMM-Newton detection, will fully explore the X-ray properties of this remarkable CV, such as spin-down rate, soft time lag, white dwarf mass measurement and search for non-thermal X-ray pulsation.
