Pulsar Birthrates from the Parkes Multibeam Survey
Pulsar Birthrates from the Parkes Multibeam Survey
We investigate the pulsar birthrate from a sample of 815 nonrecycled pulsars detected by the Parkes multibeam survey, accounting as accurately as possible for all known selection effects. We find that pulsars with magnetic fields greater than 2.5 × 1012 G account for more than half of the total birthrate …
