Parkes observations for project P786 semester 2011APRS
We have discovered 44 RRATs (eRRATic neutron stars) in archival Parkes pulsar surveys. Additionally the ongoing HTRU survey has identified 10s of excellent new candidates. These RRATs are neutron stars which emit sporadic radio bursts. Constraining and characterising the RRAT population is the motive for our work. These follow-up observations will ... morehelp us determine how neutron stars detected as RRATs are related to the general pulsar and magnetar populations. Furthermore, they will tell us about radio intermittency in neutron stars, especially those which are oldy/dying and those with strong magnetic fields. We hope to use the Parkes telescope to study our newly discovered sources through precise timing observations. 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
