Abstract

Calculations of angles \(\beta \) between magnetic moments and rotation axes have been carried out for radio pulsars located at different distances from the “death line.” We have shown that these angles decrease from 36° to 10° when pulsars move to the “death line”. Such values correspond to kinematic ages from 1 to 10 millions of years. We also argue that radio luminosities of pulsars decrease for these ages. This means that radio pulsars fade out when their age increases.
