Resonance nonlinear reflection from neutron star and additional radiation components of Crab pulsar

TL;DR

This paper investigates how resonance effects at the neutron star surface cause nonlinear reflection and generate additional high-frequency radiation components in the Crab pulsar, involving stimulated scattering and surface wave interactions.

Contribution

It introduces a model explaining high-frequency pulsar radiation components through resonance with surface electromagnetic waves and nonlinear reflection mechanisms.

Findings

Resonance with surface electromagnetic waves leads to nonlinear reflection.

Stimulated scattering generates additional high-frequency radiation components.

The model explains observed pulsar radiation features.

Abstract

Additional high-frequency components of the pulsar radiation in Crab Nebula are considered as a result of the resonance with the surface electromagnetic wave at nonlinear reflection from of the neutron star surface.This stimulated scattering consists in generation of a surface periodic relief by an incident field and diffraction on that relief the radiation of relativistic positrons, which fly from the magnetosphere to the star in the accelerating electric field of a polar gap.
