Spatial distribution of pulsars

摘要

The spatial distributions of pulsars with ages of less than 10(6) years and more than 10(6) years are shown to be quite different. The spatial distributions of pulsars with ages of less than 10(6) years and of the remnants of supernova outbursts are essentially the same. They lie near the galactic plane in a thin zone of width 400 pc. The overwhelming majority of pulsars with ages exceeding 10(6) years lie outside this zone. These facts suggest a genetic relationship between pulsars and supernova remnants. The spatial distribution of pulsars with different emission periods also supports this point.
