Predicting Ranges for Pulsars' Braking Indices

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.
