The role of multipolar magnetic fields in pulsar magnetospheres
Estelle Asseo, David Khechinashvili
We explore the role of complex multipolar magnetic fields in determining physical processes near the surface of rotation powered pulsars. We model the actual magnetic field as the…
Extraordinary features of pair plasma and \\quasilinear theory of Cherenkov-drift instability
David Shapakidze, George Machabeli, George Melikidze +1
We examine linear and quasi-liner stages of Cherenkov-drift instability in the relativistic magnetized electron-positron plasma. The external magnetic field lines are assumed to be…
On the optical pulsations from the Geminga pulsar
Janusz Gil, David Khechinashvili, George Melikidze
We present a model for generation mechanisms of the optical pulsations recently detected from the Geminga pulsar. We argue that this is just a synchrotron radiation emitted along o…
Nature of microstructure in pulsar radio emission
George Machabeli, David Khechinashvili, George Melikidze +1
We present a model for microstructure in pulsar radio emission. We propose that micropulses result from the alteration of the radio wave generation region by nearly transverse drif…
Nature of eclipsing pulsars
David Khechinashvili, George Melikidze, Janusz Gil
We present a model for pulsar radio eclipses in some binary systems, and test this model for PSRs B1957+20 and J2051-0827. We suggest that in these binaries the companion stars are…
