Scientists Observer New Binary MSPs in NGC 6205

Utilizing the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have detected a new binary millisecond pulsar (MSP) in the globular cluster NGC 6205.Scientists Observer New Binary MSPs in NGC 6205

The newly discovered pulsar got designation PSR J1641+3627F. The finding is revealed in a paper published on February 14 on the arXiv pre-print repository.

Pulsars are heavily magnetized, rotating neutron stars emitting a beam of electromagnetic radiation. The most rapidly rotating pulsars, with rotation intervals under 30 milliseconds, are known as MSPs.

Astronomers believe that MSPs form in binary systems when the initially more massive part becomes a neutron star that’s then spun-up due to accretion of matter from the secondary star.

Observations noted so far appear to support this concept, as over half of known MSPs had been found to have stellar partners.

Now, a group of astronomers headed by Lin Wang of the Chinese Academy of Sciences (CAS) Key Laboratory of FAST in China, reviews the detection of a new MSP in the vibrant globular cluster NGC 6205, which is placed some 23,150 light-years away in the constellation of Hercules.

The breakthrough was made as a part of FAST observations of NGC 6205 that further monitored other pulsars in this cluster.

Based on the research, PSR J1641+3627F has a spin interval of roughly 3.0 milliseconds and an orbital interval of 1.38 days. This means that it has the second shortest spin interval and the longest orbital period among the six pulsars, which were found in NGC 6205.
