FAST Telescope Detects New Pulsar PSR J1922+37 in Open Cluster NGC 6791

A brand new pulsar, PSR J1922+37, has been found with a spin interval of 1.92 seconds utilizing the Five-hundred-metre Aperture Spherical Radio Telescope (FAST) in China, in accordance with a report. The discovering was made within the course of the open cluster NGC 6791. If confirmed as a member of this cluster, it could be the primary pulsar recognized in an open cluster, a breakthrough in pulsar and stellar cluster analysis, in accordance with sources.

Key Details of PSR J1922+37

The discovering was reported in a paper published Dec. 11 on the arXiv preprint server. As per stories, the pulsar PSR J1922+37 has been noticed with a dispersion measure of 85 laptop/cm³ and a flux density of roughly 7.0 µJy. Its place aligns intently with the placement of NGC 6791, with an offset of 14 arcminutes from the cluster’s centre. The estimated distance of the pulsar, 15,600 light-years, is per the cluster’s distance vary, which is calculated to be between 13,100 and 16,000 light-years.

According to the research, led by Xiao-Jin Liu of Beijing Normal University, the dense stellar atmosphere of NGC 6791 will increase the probability of pulsars being current inside the cluster. Researchers have recommended that exact measurements of PSR J1922+37’s distance and correct movement will likely be needed to verify its affiliation with NGC 6791.

Potential for Further Discoveries

The researchers indicated that NGC 6791’s compact and excessive floor brightness atmosphere might host extra pulsars. An estimate supplied within the research predicts that as many as 9 pulsars could exist inside this cluster. The staff famous that additional observations utilizing superior strategies might assist confirm these predictions.

The report additional highlights that the invention has been described as a big growth within the understanding of pulsars inside open clusters, an space of research beforehand restricted resulting from low stellar density in such areas. Verification of PSR J1922+37’s cluster membership would require extra research, together with correct movement evaluation to ascertain a definitive connection.
