Two-stream Instability in Pulsar Magnetospheres
V. V. Usov
Creation of electron-positron pairs near the pulsar surface and the parameters of plasma in pulsar magnetospheres are discussed. It is argued that the pair creation process is nons…
The observational appearance of strange stars
Vladimir V. Usov
Strange quark matter with the density of ~ 5\times 10^{14} g cm^{-3} might exist up to the surface of a strange star. This differs qualitatively from the case of a neutron star and…
Low Frequency Radio Pulses from Gamma-Ray Bursts?
Vladimir V. Usov, Jonathan I. Katz
Gamma-ray bursts, if they are generated in the process of interaction between relativistic strongly magnetized winds and an ambient medium, may be accompanied by very short pulses…
Radiating Regions in Pulsar Magnetospheres: From Theory to Observations and Back
Vladimir V. Usov
We discuss plausible locations of radiating regions in the magnetospheres of pulsars and argue that the mechanisms of pulsar radiation at different frequencies are closely connecte…
Radiation from Relativistic Strongly Magnetized Outflows
Vladimir V. Usov
Relativistic strongly magnetized winds outflowing from fast-rotating compact objects like millisecond pulsars with surface magnetic fields of G are plausible…
Physical processes in pulsar magnetospheres and non-thermal high-frequency emission
Vladimir V. Usov
The energy source of a pulsar's non-thermal emission is the rotational energy loss of the neutron star. The rotational energy of the neutron star is transformed into the pulsar rad…
