Nonbirefringent model of orthogonal polarization modes in radio pulsars - New view on S swing and mode structure in pulsar beam
J. Dyks, A. Frankowski
Two orthogonal polarization modes observed in radio pulsar signals have long been attributed to proper modes of wave oscillation in strongly magnetized plasma. Yet it has been show…
Orthogonal polarization modes of nonbirefringent origin in a geometric radio pulsar signal model
J. Dyks, L. Saha, A. Frankowski
Motion of plasma in pulsar magnetospheres essentially follows bent magnetic field lines which may result in radiation beams sweeping past the observer's sightline. We show that und…
Rapid Rotation of Polarization Orientations in PSR B1919+21's Single Pulses: Implications On Pulsar's Magnetospheric Dynamics
Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks +5
We analyze and model rapid rotations of polarization orientations in PSR B1919+21's single pulses based on Five-hundred-meter Aperture Spherical radio Telescope observation data. I…
PSR B0943+10: Mode Switch, Polar Cap Geometry, and Orthogonally Polarized Radiation
Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks +10
As one of the paradigm examples to probe into pulsar magnetospheric dynamics, PSR B0943+10 (J0946+0951) manifests representatively, showing mode switch, orthogonal polarization and…
Evidence for scattering of curvature radiation in radio pulsar profiles
J. Dyks
Radio pulsars exhibit several unexplained phenomena, in particular the average pulse profiles with the apparent core-cone structure and interesting frequency evolution. I show that…
A new model for nulling and moding in radio pulsars
J. Dyks
Single pulse behaviour of radio pulsars is usually interpreted in terms of the ExB drift of a radio beam. It is shown that antisymmetric arrangement of the radio-bright zones can p…
