Discovery of a Nearby Ultra-fast Magnetic White Dwarf Propeller: Common Pathways to Magnetic Cataclysmic Variables
The discovery of 1eRASS J042633.5−250226, a nearby magnetic white dwarf propeller, confirms them as ultra-rapidly spinning magnetized WDs. This system's properties suggest that WD propellers are a common early stage in the evolution of magnetic cataclysmic variables, implying a local space density comparable to other magnetic CVs.
