Decoding the Cataclysmic Outburst: Study Focuses on GK Persei

The analysis identified a white dwarf spin period of 351.32 seconds and found spin modulation in the softer energy band during later observations of the 2010 outburst. Researchers also observed significant variations in mass accretion rates across different outbursts, with 2010 and 2018 values lower than in 2015. Their results suggest that GK Persei’s soft X-ray emissions likely originate from both its magnetic poles and surrounding circumstellar material, advancing the understanding of magnetic cataclysmic variables exhibiting dwarf nova behavior.
