Electromagnetic emission from blitzars and its impact on non-repeating fast radio bursts

Understand

It has been suggested that a non-repeating fast radio burst (FRB) represents the final signal of a magnetized neutron star collapsing to a black hole.

• In this model, a supramassive neutron star supported by rapid rotation, will collapse to a black hole several thousand to million years after its birth as a result of spin down.
• The collapse violently snaps the magnetic-field lines anchored on the stellar surface, thus producing an electromagnetic pulse that will propagate outwards and accelerate electrons producing a massive radio burst, i.e.
• a "blitzar".
