Parkes observations for project P786 semester 2011OCTS
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. Their sporadic emission makes them difficult to study, and nearly all information about the properti... morees 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 RRAT properties and origins. Through RRAT monitoring and timing, we will continue to determine basic RRAT properties. This will enable us to identify physical causes for the extreme RRAT emission, deduce how RRATs 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
