Comments on "Strongly magnetized cold degenerate electron gas: Mass-radius relation of the magnetized white dwarf"

TL;DR

This paper critiques previous models of super-massive magnetized white dwarfs, highlighting that neglecting Lorentz forces leads to models far from equilibrium, thus questioning their physical validity.

Contribution

It clarifies the importance of including Lorentz forces in modeling magnetized white dwarfs, challenging prior assumptions of equilibrium in such models.

Findings

Previous models neglect Lorentz forces, leading to unrealistic equilibrium assumptions.

Inclusion of Lorentz forces is essential for physically accurate white dwarf models.

Critique emphasizes the need for revised modeling approaches considering magnetic forces.

Abstract

The super-massive white dwarf models proposed by Das & Mukhopadhyaya [Phys. Rev. D 86 042001 (2012)], based on modifying the equation of state by a super-strong magnetic field in the centre, are very far from equilibrium because of the neglect of Lorentz forces, as has recently been shown by Nityananda & Konar [arXiv:1306.1625].
