What is Rapidly Spinning White Dwarf LAMOST J0240 about?

LAMOST J024048.51+195226.9 is a cataclysmic variable star with a rapidly spinning white dwarf that has a spin period of 24.93 seconds, making it the shortest known spin period for such stars. The white dwarf has a mass of at least 0.7 times that of the Sun and exhibits pulsations with a pulse amplitude of approximately 0.2% in the g-band. This discovery establishes it as the second known white dwarf magnetic propeller system, alongside AE Aquarii.
