Relation of pulsars to the remnants of supernova bursts

摘要

Based on a large volume of statistical data it is shown that the spatial distributions of radio pulsars in the galaxy with characteristic ages T <= 10(6) years and T > 10(6) years differ significantly. The overwhelming majority of the pulsars with T <= 10(6) years lie within a narrow band of width 400 pc around the galactic plane. A large portion of the pulsars with T > 10(6) years is concentrated outside this zone. In the case of younger pulsars, a larger fraction of them lies within the confines of the above mentioned zone. It is also shown that pulsars with T <= 10(6) years and the remnants of supernova explosions have essentially the same spatial distribution. These facts support the existence of a relationship between pulsars and supernova remnants, as well as the acquisition of high spatial velocities by pulsars during their birth.
