A Non-radial Oscillation Model for Radio Pulsars

April 7

12:10PM, Room 230, NRAO, Edgemont Road


We present a non-radial oscillation model that can successfully reproduce many properties of drifting subpulses in pulsars. By demonstrating the presence of oscillation modes in pulsars, we hope to pave the way for astroseismology of neutron stars. This model is an alternative to the drifting spark model of Ruderman and Sutherland (1975). This behavior includes the time-averaged pulse properties, the individual pulse properties, and the subpulse phase jumps and orthogonal polarization modes. We show that our model can be successfully fit to the data by conducting a quantitative analysis of PSR 0943+10.
