We present an energy functional for a Thomas-Fermi type two-fluid model of a self-gravitating non-rotating charged body, with a non-relativistic kinetic energy. We prove that, under certain conditions on the total number of positively charged and neg

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 thes

To approximately compute the non-relativistic ground state of an electrically non-neutral star, an exactly solvable model was recently introduced, and partly solved, by Krivoruchenko, Nadyozhin, and Yudin. The model generalizes the well-known Lane--E

The question how much surplus of electric charge ("surcharge") fits on an object is generally very difficult to answer. Here it is shown that it is easy to answer when the object is a \emph{failed white dwarf} star (a brown dwarf in its ground state)

We examine the consequences of removing the electric neutrality assumption on the old stellar models of Lane, Emden, Chandrasekhar, and others. Section 1 presents a review of these older models as well as a discussion of current research. Section 2 p
