A Broadband X-ray Investigation of Fast-Spinning Intermediate Polar CTCV J2056-3014
Ciro Salcedo, Kaya Mori, Gabriel Bridges +5
We report on XMM-Newton, NuSTAR, and NICER X-ray observations of CTCV J2056-3014, a cataclysmic variable (CV) with one of the fastest-spinning white dwarfs (WDs) at P = 29.6 s. Whi…
