An article published in the journal “Nature Astronomy” reports an analysis of an irregularity in the spin, a phenomenon called glitch in jargon, in the Vela Pulsar. A team of researchers led by Gregory Ashton of Monash University, Australia, analyzed the data collected by the Mount Pleasant Radio Observatory of the glitch detected on December 12, 2016. Probably this phenomenon is caused by internal interactions in the pulsar materials so studying it can provide information on the internal composition and on the processes taking place in an extreme object of this type.
