"Study Unveils Enormous 'Spider' Pulsar"

Astronomers from Stanford University have conducted joint X-ray and optical observations of the massive "spider" pulsar PSR J2215+5135, revealing new insights into its nature. The study found that the neutron star in the system has a mass of approximately 2.15 solar masses and that the companion star loses mass at a rate of 0.0003 Earth masses per year. The findings suggest that J2215 may eventually become an isolated millisecond pulsar.

"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.
