摘要: RX J1914.4 + 2456 exhibits a light curve with strong modulation at 569 s: this period is characteristic of the white dwarf spin in intermediate polar (IF) systems. However, X-ray difficult to reconcile current models for IP emission. We argue that simpler explanation system degenerate secondary star, which would make it first known its kind. As such should contain example an He-dominated radial accretion flow on surface, and have shortest orbital any binary system.
