Abstract

The pulsar J0901–4046 has a spin periodP = 75.8 s and is themost slowly rotating one among
the isolated radio pulsars. We have considered the influence of a small-scale magnetic field in the offcentered
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.
