Scientists use X-rays to reveal speed of neutron star jets | If they can determine how jet speeds vary with the mass or spin of the neutron star, that would provide a powerful test of theoretical predictions.


Astronomers measured neutron star jets, reaching one-third light speed. They utilized X-ray bursts to time the jet launch.

For the first time, astronomers have clocked how fast neutron stars drive powerful jets into space. Cosmic beams that are launched when dust or gas gravitate towards dense objects, like neutron stars (the remnants of a once-massive star). In an article penned in The Conversation, James Miller-Jones, a Professor at Curtin University and co-author of the study, explained that the jets carry away gravitational energy released by the infalling gas.
