Description

Coherent pulsar radio emission requires an existence of inner acceleration region above the polar cap. The most advanced implementation of the inner gap idea is the Partially Screened Gap (PSG) model, based on recent calculations of the surface binding energy and Hall drift induced surface magnetic field in neutron stars. The PSG model has a great predictive power and can be tested observationally both in radio band and X-rays. PSR B0943+10, which was extensively observed and studied in both these bands, is an ideal testing case. We demonstrate that all the observational characteristics of PSR B0943+10 are fully consitent with the PSG pulsar model. This has important consequences for understanding the physics of pulsar radio emission mechanism.
