Space plasma under extreme conditions

  title={Space plasma under extreme conditions},
  author={Vladimir V. Zheleznyakov},
  journal={Radiophysics and Quantum Electronics},
Attributes of extreme conditions in space and the new properties which plasma acquires in this case are discussed. The discussion is focussed on the features of interaction between plasma and radiation in strong magnetic fields of degenerate stars—white dwarfs or neutron stars. The specific role of cyclotron scattering, radiation pressure at cyclotron frequencies, and vacuum birefringence in the formation of plasma envelopes and the observed spectra of these objects is pointed out.

Interaction of hot plasma with radiation of magnetic white dwarfs

On the theory of X-ray pulsar radiation
The origin of hard X-ray spectrum (continuum and cyclotron lines) of pulsars in binary systems is discussed. A model of the polar region of a neutron star consisting of a hot spot in a dense plasmaExpand
The effect of vacuum birefringence on the polarization of X-ray binaries and pulsars
In a strong magnetic field the vacuum becomes birefringent. This effect is especially important for pulsars at X-ray wavelengths. Any polarized X-ray emission from the surface of a magnetic neutronExpand

On hard X-ray spectra of accreting neutron stars
Formation of the spectra of X-ray pulsars and gamma bursters is investigated. Interpretation of a hard X-ray spectrum of pulsars containing cyclotron lines is feasible on the basis of an isothermalExpand
It is well known from pulsar physics that neutron stars must possess surface magnetic fields of the order of loio to lo” gauss or possibly even higher. These figures are derived from considerationsExpand
Gamma-ray bursts and very high energy gamma-ray astronomy
The current status of gamma-ray burst astronomy is reviewed briefly, with emphasis on experiments which might determine the burster distance scale. Recent observations by the EGRET experiment aboardExpand
Evidence for strong cyclotron line emission in the hard X-ray spectrum of Hercules X-1
We present further results of our Hercules X-1 balloon observation on 1976 May 3 which confirm the existence of a strong line feature at approx.58 keV in the pulsed (1.24s) X-ray spectrum we reportedExpand
Photon splitting and photon dispersion in a strong magnetic field
We determine the refractive indices for photon propagation, and the absorption coefficient and polarization selection rules for photon splitting, in a strong constant magnetic field. Results areExpand
