How much electric surcharge fits on ... a white dwarf star?

Abstract
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) made of protons and electrons: Given the number of protons, how many electrons can there be? Surprisingly, the answer (in the form: as few as and as many as ) is independent of the speed of light and the Planck quantum , even when the star is stabilized against collapse by relativistic quantum mechanics.
arXiv comment9 pages, 3 figures. This revision contains about 1/3 of v1, slightly expanded, and will appear in Am. J. Phys. It no longer contains the exactly solvable model. The remaining 2/3 of v1 with the exactly solvable model have been expanded significantly into a new paper in its own right, to be published separately
