Parkes observations for project P511 semester 2006OCTS
We request continuing observations of 11 rotating radio transients. These sources appear to be rotating neutron stars, but they are detectable only through their sporadic radio bursts. The observations proposed here are crucial for understanding the emission mechanism of these sources and for determining how they relate to other neutron star popula... moretions. Through monitoring observations of all sources, we aim to further contrain burst flux distributions and properties and search for any new and unexpected bursting phenomena. Further timing observations of the four sources with measured period derivatives are essential for refining positions, searching for glitches or other timing abnormalities and placing limits on any underlying normal pulsed radio emission. For the other sources, our new timing strategy should yield period derivatives, which will allow us to determine accurate positions and infer magnetic fields and characteristic ages, essential for comparing these sources with other classes of neutron stars. We also request an additional observation aimed at measuring burst spectral indices. These observations are the cornerstone of an extensive campaign at X-ray, radio and infrared wavelengths and are absolutely essential if we are to understand these mysterious objects. less

P511 - Further Investigations into a New Class of Radio Transients
Neutron stars are of interest to a broad range of astronomers and physicists. They can be used to probe equations of state of superdense matter, to study plasma and particle physics, and to test theories of general relativity and even cosmology. We have found an entirely new class of these objects which are radio emitters for less than 1 second a d... moreay! Understanding how these objects emit is very important for neutron star astrophysics and has huge implications for the total number of such stars in our Galaxy. We expect many more of these objects to be found by large field of view instruments such as LOFAR and the SKA. less
