X-ray pulsar radiation from polar caps heated by back-flow bombardment.
GIL J., MELIKIDZE G. and ZHANG B.
Abstract (from CDS):
In this Letter we consider two more pulsars: PSRs B0656+14 and B0628-28, the data for which have recently become available. In PSR B0656+14 the thermal radiation from the hot polar cap was clearly detected, and PSR B0628-28 also seems to have such a component.
In all cases for which both P4 and Lxare presently known, the PSG pulsar model seems to be fully confirmed. Other available models of inner acceleration region fail to explain the observed relationship between radio and X-ray data. The pure vacuum gap model predicts too high Lx and too low P4, while the space charge limited model predicts too low Lx and the origin of the subpulse drift has no natural explanation.
