Comment on "Strong constraints on magnetized white dwarfs surpassing the Chandrasekhar mass limit"

TL;DR

This paper critically examines previous claims about the magnetic field limits of super-Chandrasekhar white dwarfs, identifying errors that support their stability and challenging earlier conclusions.

Contribution

It provides a corrected analysis of magnetic field bounds in super-Chandrasekhar white dwarfs, refuting prior erroneous calculations and supporting their potential stability.

Findings

Previous bounds on magnetic fields were incorrect

Corrected calculations support stability of super-Chandrasekhar white dwarfs

Identified numerical errors in prior work

Abstract

We show that the upper bound for the central magnetic field of a super-Chandrasekhar white dwarf calculated by Nityananda and Konar [Phys. Rev. D 89, 103017 (2014)] is completely erroneous. This in turn strengthens the argument in favor of the stability of the recently proposed magnetized super-Chandrasekhar white dwarfs. We also point out several other numerical errors in their work. Overall we conclude, based on our calculations, that the arguments put forth by Nityananda and Konar are fallacious and misleading.
