A model for unusual pulsed x-ray emission from PSR J1119-6127

We propose a model, which naturally explains an unusual thermal X-ray emission, observed from PSR J1119-6127. The model is based on the assumption that the pulsar magnetic field near the stellar surface differs significantly from the pure dipole field. We show that the structure and curvature of the field lines can be of the kind that allows the pair creation in the closed field line region. The created pairs propagate along the closed field lines and heat the stellar surface beyond the local poles. It is demonstrated that such a configuration can be easily realized.
