Total Time Requested: 3 Hours
Proposal Title: A Search for Radio Pulsations from an Isolated Neutron Star
ABSTRACT:
We propose a search for radio pulsations from the neutron star candidate RBS1223 (1RXS
J130848.6+212708), discovered recently as part of the ROSAT Bright Survey. Our request is for 3 hours
of telescope time over two days, for observations using both the PSPM and AOFTM to obtain
fast-sampled pulsar search data. No periodicity has been seen in the X-ray data, but the number of
photons is small. If radio emission is detected, our search will determine the neutron star's rotation rate
and, through subsequent timing, its age, magnetic eld strength, and distance. The absence of any radio
pulsations will also provide important (model-dependent) constraints on the emission geometry while
contributing another data point to the small handful of poorly understood radio-quiet neutron stars.
