Mechanism of generation of the emission bands in the dynamic spectrum of the Crab pulsar
H. Ardavan, A. Ardavan, J. Singleton +1
We show that the proportionately spaced emission bands in the dynamic spectrum of the Crab pulsar (Hankins T. H. & Eilek J. A., 2007, ApJ, 670, 693) fit the oscillations of the squ…
Spectral properties of the nonspherically decaying radiation generated by a rotating superluminal source
Houshang Ardavan, Arzhang Ardavan, John Singleton +2
The focusing of the radiation generated by a polarization current with a superluminally rotating distribution pattern is of a higher order in the plane of rotation than in other di…
The fundamental role of the retarded potential in the electrodynamics of superluminal sources
Houshang Ardavan, Arzhang Ardavan, John Singleton +2
We calculate the gradient of the radiation field generated by a polarization current with a superluminally rotating distribution pattern and show that the absolute value of this gr…
Occurrence of concurrent `orthogonal' polarization modes in the Lienard-Wichert field of a rotating superluminal source
A. Schmidt, H. Ardavan, J. Fasel +2
We evaluate the Lienard-Wiechert field of a rotating superluminal point source numerically and show that this radiation field has the following intrinsic characteristics. (i) It is…
Violation of the inverse square law by the emissions of supersonically and superluminally moving volume sources
H. Ardavan, J. E. Ffowcs Williams
The generally familiar notion that the conservation of energy requires the intensity of the radiation generated by a localized finite-duration source to decay like the inverse squa…
Splitting of the Alfven surface in a relativistic pulsar wind
H. Ardavan
In a recent paper, Li and Melrose have claimed that the splitting - due to relativistic effects - of the Alfven surface in an axisymmetric pulsar wind does not occur. Here we refut…
