Astronomers find first strong evidence of neu

<p>In the study, published in the journal <em>Science</em>, researchers used two instruments on the James Webb Space Telescope (JWST), MIRI and NIRSpec, to observe the supernova at infrared wavelengths and found evidence of heavy argon and sulphur atoms whose outer electrons had been stripped off (i.e. the atoms had been ionised) close to where the star explosion occurred.</p>

<p>The team modelled various scenarios and found that these atoms could only have been ionised by ultra-violet and X-ray radiation from a hot cooling neutron star or, alternatively, from the winds of relativistic particles accelerated by a rapidly rotating neutron star and interacting with surrounding supernova material (pulsar wind nebula).</p>

Newly born neutron star detected in nearby supernova

An international team of astronomers including UCL’s Professor Mike Barlow has discovered the first conclusive evidence that a neutron star exists at the centre of Supernova 1987A, a star explosion observed 37 years ago. ....
