Bursting pulsar found to 'hiccup' during crucial stage of its lifecycle

Post by Dragon on Wed May 09, 2018 10:38 pm

Researchers at the University of Southampton have discovered that the unique 'Bursting Pulsar' – a neutron star which steals matter from a low-mass stellar neighbour – may also be the slowest known 'transitional pulsar' in existence. Transitional pulsars are a rare class of neutron stars, which alternate between showing X-ray and radio pulsations over timescales of years.

About 20 km around, the density of a neutron star attracts matter from a companion star.

Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes. Others had shown that the high-speed particle jets needed to make a gamma-ray burst would continue if placed in the swirling wreckage of a recent merger.

Now, the simulations reveal the middle step of the process--how the merging stars' magnetic field organizes itself into outwardly directed components capable of forming a jet.
