ABSTRACT

Petrova S.A. The propagation of radio emission in pulsar
magnetospheres. — Manuscript.

Dissertation for the scientific degree of the candidate of physical and
mathematical sciences on the speciality 01.03.02 — astrophysics and
radioastronomy. — The Main Astronomical Observatory of National Academy
of Science of Ukraine, Kyiv, 1999.

The thesis is devoted to the investigation of radio wave propagation in
an ultrarelativistic highly magnetized pulsar plasma. Refraction,
polarization evolution, synchrotron absorption and induced scattering of
radio emission are considered. The observational consequences of these
effects are analysed as well.

Refraction of ordinary superluminous waves is treated on the basis of
Hamilton’s equations. Obtained numerical solutions permit to outline the
characteristic features of radio wave behaviour in pulsar plasma.
Refraction appears to occur mainly on account of plasma density gradient
across the open field line tube, the ray deviation being directed
oppositely to the gradient. At large distances from the neutron star the
plasma flow widens, so that transverse density gradient decreases and
refraction ceases. Given that the radiation at a given frequency
originates at a corresponding radius refraction should be essentially
dependent on the frequency.

In the plasma with the density decreasing towards the tube edge the
rays deviate away from the magnetic axis causing the enhancement of the
observed pulse width. At high frequencies refraction is found to
contribute essentially to the pulse width, while at low ones the pulse
width is chiefly determined by the open field line tube width. Thus at
high frequencies the pulse width remains almost constant and at low ones
it increases with the wavelength. Such dependence is compatible with the
pulse width versus frequency curves observed for a number of pulsars.

Provided that the plasma density increases outwards the tube the rays
should deviate towards the magnetic axis. The deviation increases with
the frequency and leads to the corresponding decrease of the pulse
width. At least the rays begin to intersect the axis. Then they form the
opposite half of the profile, the pulse width increasing with the
frequency. The rays emitted at still higher frequencies have time to
start deviation in the opposite direction due to oppositely directed
transverse density gradient in the region beyond the magnetic axis. This
results in repeat decrease of the pulse width. Such dependence of the
pulse width upon the frequency agrees with the curves with the so called
“absorption feature” observed for some pulsars.

Polarization transfer of normal waves in the rotating magnetosphere is
examined. The ultrarelativistic plasma embedded in a superstrong
magnetic field allows two nondamping normal waves. In the emission
region, they are linearly polarized. While propagating inside the
magnetosphere, the waves are influenced by the plasma. The emergent
polarization is known to be set up by the wave mode coupling in the
polarization-limiting region. As a result of this effect the outgoing
radiation should be elliptically polarized, with the sense of the
circular component being the same throughout the pulse. The quantitative
description of the polarization evolution is carried out proceeding from
Maxwell’s equations together with the equation of plasma particle motion
in the rotating magnetosphere. It is shown that at pulsar conditions the
final degree of circular polarization due to the wave mode coupling
ranges from a few to dozens per cents. The polarization profiles are
compatible with those observed for a number of pulsars.

Resonance absorption of pulsar radiation by the plasma particles is
studied. Cyclotron absorption is known to be significant in pulsar
magnetospheres. It is found that as a result of this process the
particles can readily acquire relativistic gyration energies. General
theory of synchrotron absorption is developed in terms of the Einstein’s
coefficient method. The absorption coefficients for ordinary and
extraordinary waves are also obtained by plasma methods. As long as the
energy absorbed is less than the initial plasma energy both the
frequency of the absorbed radiation and the absorption coefficients
remain the same as in the cyclotron case. Corresponding absorption depth
appears to be high, especially in the short-period pulsars. The radio
wave escape from the magnetosphere then can be explained only by the
nonuniformity of plasma distribution within the open field line tube. In
short-period pulsars, a significant fraction of the energy absorbed is
found to be reemitted spontaneously in the far infrared band.

The induced scattering of pulsar radio emission by the plasma particles
is investigated. Kinetic equations describing the change of photon
occupation numbers in the course of the scattering are deduced. It is
shown that at pulsar conditions the induced scattering from the beam to
a background always dominates over the scattering inside the beam. The
process turns out to be intense at frequencies ( 100 MHz. It can account
for the low — frequency turnovers observed in pulsar spectra.

Key words: pulsars, radio wave propagation, ultrarelativistic highly
magnetized plasma, refraction, wave mode coupling, limiting
polarization, synchrotron absorption, induced scattering.
