Predicting Ranges for Pulsars' Braking Indices

TL;DR

This paper proposes a modified model for pulsars' braking indices, using observational data to predict ranges for pulsars with unknown indices, advancing understanding of pulsar spin-down behavior.

Contribution

It introduces a modified canonical model for pulsars and applies it to predict braking index ranges for pulsars lacking direct measurements.

Findings

Predicted braking index ranges for several pulsars.

Validated the modified model against known pulsar data.

Enhanced the theoretical framework for pulsar spin-down analysis.

Abstract

The theoretical determination of braking indices of pulsars is still an open problem. In this paper we report results of a study concerning such determination based on a modification of the canonical model, which admits that pulsars are rotating magnetic dipoles, and on data from the seven pulsars with known braking indices. In order to test the modified model we predict ranges for the braking indices of other pulsars.
