Description
New surveys by the FAST and MeerKAT observatories have enabled, for the first time, a robust statistical study of orthogonal pulsars using large homogeneous samples. These objects, with magnetic axis nearly perpendicular to the rotation axis, are particularly sensitive to magnetospheric physics and serve as a key test for neutron star evolution models. We show that the statistical properties of orthogonal interpulse pulsars—specifically their period distribution and relative abundance are inconsistent with modern numerical models. To improve our understanding of orthogonal pulsars, we develop a novel method for determining the three-dimensional structure of the accelerating potential above the polar caps. Unlike previous approaches, our method is applicable to any inclination angle, including exact orthogonal rotators. Obtained results allowed us to calculate corresponding secondary plasma transverse density profiles, which are necessary for studying pulsars mean intensity profiles and their statistics in general.
