XMM-Newton Observations of Radio Pulsars B0834+06 and B0826-34 and Implications for Pulsar Inner Accelerator
J. Gil, F. Haberl, G. Melikidze +2
We report the X-ray observations of two radio pulsars with drifting subpulses: B0834 + 06 and B0826 - 34 using \xmm\. PSR B0834 + 06 was detected with a total of 70 counts from the…
X-ray pulsar radiation from polar cap heated by back-flow bombardment
J. Gil, G. I. Melikidze, B. Zhang
We consider the problem of the thermal X-ray radiation from the hot polar cap of radio pulsars showing evidence of \EB subpulse drift in radio band. In our recent Paper I, using th…
A model for unusual pulsed x-ray emission from PSR J1119-6127
G. I. Melikidze, J. Gil, A. Szary
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 ne…
Thermal radiation from hot polar cap in pulsars
Janusz Gil, George Melikidze, Bing Zhang
Thermal radiation from hot polar caps is examined in radio pulsars with drifting subpulses. It is argued that if these subpulses correspond to sparking discharges of the inner acce…
Formation of a Partially-Screened Inner Acceleration Region in Radio Pulsars: Drifting Subpulses and Thermal X-Ray Emission from Polar Cap Surface
Janusz Gil, George Melikidze, Bing Zhang
The subpulse drifting phenomenon in pulsar radio emission is considered within the partially screened inner gap model, in which the sub-Goldreich-Julian thermionic flow of iron ion…
Interrelation between radio and X-ray signatures of drifting subpulses in pulsars
Janusz Gil, George Melikidze, Bing Zhang
We examined a model of partially screened gap region above the polar cap, in which the electron-positron plasma generated by sparking discharges coexists with thermionic flow eject…
