A new millisecond pulsar has been found in a cluster of stars. PSR J18353259B is a new pulsar. The finding and disclosure of fundamental parameters of this object was published on the arXiv pre-print server.
Nuclear stars emit a beam of radiation. The most rapidly rotating pulsars are known as millisecond pulsars. Astronomers think that they are formed in a pair of systems when one component becomes a neutron star and the other becomes a star.
An upgrade to the Giant Metrewave Radio Telescope (uGMRT) has led to the detection of another MSP. During radio observations of eight GCs at 400 MHz and 650 MHz with the new GMRT Wideband Backend (GWB) system of the UGMRT, they found that a rapidly spinning pulsar was present.
We presented the results of a GC survey we did with the new wide-bandwidth receivers of UGMRT to find steep-spectrum pulsars. Eight GCs were observed and we searched each cluster for isolated and binary pulsar systems. J18353259B was discovered in the middle of the universe.
J18353259B is a pulsar. It has a spin period of 1.83 milliseconds, a orbital period of 1.2 days, and a dispersion measure of 63.5 pc/ cm 3
The results show that PSR J18353259B has a fairly small eccentricity. The strength of the surface magnetic field is estimated to be less than 350 million Gauss by the astronomer.
According to the study, the median mass of the companion object in PSR J18353259B is 0.21 solar mass. The researchers think that the companion is a white dwarf because of the results.
In addition to the detection of PSR J18353259B, the research also estimated the densities of all the pulsars in the eight GCs. It was found that PSR J18353259B is the best of all the pulsars. The astronomer found three radio sources that were not associated with any known pulsars. They need more observations to untangle their nature.
