Comments on "Charged particle dynamics in the field of slowly rotating compact star"

TL;DR

This paper critiques and corrects a previous solution for the electromagnetic and gravitational fields of a slowly rotating neutron star, providing a mathematically consistent and physically valid alternative.

Contribution

It identifies errors in Mirza's original solution and offers a corrected, consistent solution that remains finite in the no-rotation limit.

Findings

Mirza's original solution diverges at zero rotation

The corrected solution is mathematically consistent

The new solution remains finite as rotation approaches zero

Abstract

B.M. Mirza \cite{1} presented a solution of coupled Einstein-Maxwell equations for a slowly rotating neutron star; however his derivations had some errors and implicit assumptions that rendered the solution invalid. We point out the errors and present a mathematically consistent solution. The resulting solution is also physically consistent as it remains finite in the no rotation limit, whereas Mirza's solution diverges for zero rotation.
