Self-consistent modeling of pair cascades in the polar cap of a pulsar

TL;DR

This paper presents initial results from a self-consistent simulation of non-stationary electron-positron pair cascades in pulsar polar caps, using a hybrid PIC/Monte-Carlo code to model Ruderman-Sutherland cascades without particle extraction from the neutron star surface.

Contribution

It introduces a novel hybrid simulation approach for modeling non-stationary pair cascades in pulsar polar caps, specifically focusing on Ruderman-Sutherland type cascades.

Findings

First results of the simulation are reported.

The model captures non-stationary behavior of pair cascades.

Insights into cascade dynamics without particle extraction are provided.

Abstract

Here we briefly report on first results of self-consistent simulation of non-stationary electron-positron cascades in the polar cap of pulsar using specially developed hybrid PIC/Monte-Carlo numerical code. We consider the case of Ruderman-Sutherland cascade -- when particles cannot be extracted from the surface of the neutrons star.
