Contribution

It introduces a general relativistic framework for non-neutral white dwarf stars, building on previous Newtonian models and results.

Findings

General relativistic equations for charged white dwarfs derived.

Numerical solutions compared between Newtonian and relativistic models.

Relativistic bounds on stellar charge established.

Abstract

We generalize the recent Newtonian two-component charged fluid models for white dwarf stars of Krivoruchenko, Nadyozhin and Yudin and of Hund and Kiessling to the context of general relativity. We compare the equations and numerical solutions of these models. We extend to the general relativistic setting the non-neutrality results and bounds on the stellar charge obtained by Hund and Kiessling.
