The Features of a High-magnetic Field Pulsar Are Now Reexamined

new research

Astronomers utilized space observatories and conducted multi-wavelength research of a high-field pulsar dubbed PSR J119-6127, which experienced an explosion back in 2016. Their results shed more light on the features of this pulsar during the post-blast event. 

PSR J119-6127 was spotted in 2000 by the Parkes multibeam pulsar survey, likely related to the supernova remnant G292.2-0.5 at approximately 27,400 light-years. The pulsar also has a spin period of 0.407s, a particular age of some 1,600 years, and spin-down power of about 2.3 undecillion erg/s. Here is what you need to know. 

PSR J119-6127 Under Investigation

In 2016, NASA’s Fermi and Swift spacecraft spotted magnetar-like X-ray eruptions of PSR J119-6127 and 13 short X-ray bursts. Approximately 1.0 tredecillion erg. of energy was discharged. To better understand the evolution of PSR J119-6127, researchers began to examine this pulsar. 

Now, a team of researchers realized a multi-wavelength study of PSR J119-6127. They utilized data from Swift, Fermi, ESA’s X-ray Multi-Mirror Mission (XMM-Newton), and NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR).

Before the 2016 explosion, the X-ray pulse peak of PSR J119-6127 matched its radio pulse peak. The study discovered no significant shift between these peaks after the blast. It was noted that the examined X-ray spectra of both off- and on-pulse phases are well defined by two blackbody elements and a power-law model. 

The recent study unveiled that the evolution of the timing solution, X-ray emission, and radio emission features of PSR J119-6127 after its previous discharge resembles XTE J1810-197. However, the recovery time scale and discharged total energy are one or two orders of magnitude smaller in PSR J119-6127. 

Considering all the gathered data, the researchers concluded that the 2016 X-ray explosion most likely resulted in a reconfiguration of the full magnetosphere of PSR J119-6127. It also changed the structure of the open field line regions. Researchers added that this reconfiguration went on for almost a half-year after the explosion.
