Pulsar Survey. The motivation was to understand this population better, including “Rotating Radio Transients”
(RRATs), “Fast Radio Bursts” (FRBs) and “Perytons”. RRATs are radio pulsars which can be detected in single-pulse searches more easily than periodicity searches. It is now believed that these are extreme examples of the radio pulsar population, and their pulsed emissions are either highly modulated or sufficiently infrequent.
FRBs are bright short duration (millisecond) radio bursts of extra-galactic origins. Perytons bear the signature of the radio signal getting dispersed in the interstellar medium like other celestial …show more content…
The repeating nature of one FRB (FRB121102) has ruled out the catastrophic models, unless this event is of an origin distinct from all other FRBs. I explored the possibility of FRBs being created by the infall of asteroids onto neutron stars. If there is an asteroid belt around a neutron star, then a chance infall of an asteroid from the belt to the neutron star would give rise to a non-repeating FRB. On the other hand, if a neutron star passes through an asteroid belt around another star, then there might be more than one asteroid infalls resulting in a series of FRBs. In particular, if the star surrounded by the asteroid belt is gravitationally bound to the neutron star, then the neutron star would pass through the belt repetitively, leading to a repeating series of FRBs. I pointed out the probable nature of the neutron star binary where
