Generation of nanoflares in the Crab pulsar

TL;DR

This paper explores how nonlinear drift wave dynamics in the Crab pulsar's plasma can generate nanoshots in radio emissions, linking plasma instability to observable phenomena.

Contribution

It demonstrates that nonlinear drift wave structures and cyclotron instability can produce nanoshots in pulsar radio emissions, a novel explanation for these phenomena.

Findings

Nonlinear drift waves form small-scale plasma structures.

Cyclotron instability within these structures can generate nanoshots.

The mechanism explains observed nanoshots in Crab pulsar radio signals.

Abstract

We study dynamics of drift waves in the pair plasma of pulsar magnetosphere. It is shown that nonlinear of the drift waves with plasma particles leads to the formation of small scale structures. We show that cyclotron instability developed within these nonlinear structures can be responsible for the formation of nanoshots discovered in the radio emission of the Crab pulsar.
