Abstract

The pulsar J0901–4046 has a spin period \(P=75.8\) s and is the most slowly rotating one among the isolated radio pulsars. We have considered the influence of a small-scale magnetic field in the off-centered dipole model on the polar cap heating by the reverse positron current in the inner gap of the pulsar. We have assumed that the electron–positron pairs in the gap are created in bound states, which then are broken by thermal photons from the stellar surface.
