Parkes observations for project P786 semester 2012OCTS
Rotating Radio Transients (RRATs), neutron stars from which sporadic radio bursts are detected, represent approximately 3% (and increasing) of radio-emitting pulsars as they are found via single-pulse searches of archival and current pulsar surveys. The sporadic emission from these and intermittent pulsars makes them difficult to study and nearly a... morell information about the properties of the objects is the result of dedicated monitoring and timing programs at Parkes telescope. This project represents the largest (and most successful) effort in constraining the properties and origins of sparse-emitting pulsars. Through monitoring and timing, we will continue to determine basic RRAT and intermittent pulsar properties. This will enable us to identify physical causes for the extreme emission, deduce how these pulsars are related to the general pulsar and magnetar populations, and explore the distribution of extreme radio intermittence in neutron stars. less

P786 - Transient Radio Neutron Stars
In 2006 a number of neutron stars were discovered by astronomers. These new sources - dubbed RRATs (eRRATic neutron stars) were seen to emit bursts of radio emission every few minutes. Neutron stars are the remnants of stellar explosions (supernovae) which occur in massive stars once they have reached the ends of their lives. The discovery of such ... moresporadic behaviour was not expected but understanding it is vital to explain radio emission in neutron stars. To explain this and other interesting aspects of the RRAT phenomenon we are searching for, and indeed have successfully discovered more sources, which we are now studying to try to understand RRAT behaviour. less
