Abstract: | Parameters of 100 radio pulsars detected outside the radio range (he pulsars) are compared with those of pulsars radiating only in the radio (n pulsars). The periods of he pulsars are, on average, appreciably shorter than those of n pulsars: 〈P〉 = 0.10 and 0.56 s, respectively. The distribution of the magnetic field at the light cylinder is shifted toward higher magnetic fields for the pulsars with high-energy radiation, compared to the distribution for pulsars radiating only in the radio. The magnetic fields at the light cylinder are 〈B lc〉 = 9×103 G for he radio pulsars, and 〈Blc〉 = 56 G formost purely radio pulsars. This suggests the generation of high-energy nonthermal radiation in radio pulsars at the peripheries of their magnetospheres. The distribution of the spin-energy loss rate dE/dt is uniform for he pulsars, and is characterized by a higher average value (left( {leftlangle {log frac{{dE}} {{dt}}} rightrangle = 35.53} right) ) , compared to n pulsars, (left( {leftlangle {log frac{{dE}} {{dt}}} rightrangle = 32.60} right) ) . The spatial distribution of he pulsars is nonuniform: they form two well separated clouds. |
