"Breakthrough Discovery: Giant Radio Telescope Uncovers Evolutionary Link in Spider Pulsar System"

Researchers using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) have discovered a binary pulsar system, named PSR J1953+1844 or M71E, with a 53-minute orbital period. This discovery fills the gap in the evolution of spider pulsar systems, confirming the theoretical path from redback to black widow states. The findings provide new insights into the behavior of these fascinating objects and were published in Nature.

Green Bank Telescope discovers binary pulsar with 53-minute orbit

Radio observations of the binary millisecond pulsar PSR J1953+1844 (M71E) show it to have an orbital period of 53.3 minutes and a companion with a mass of ~0.07 M⊙. It is a faint X-ray source and located 2.5 arcminutes from the center of the globular cluster M71. This discovery suggests the existence of a population of millisecond pulsars with moderate mass companions and very short orbital periods.
