  The structure of a star composed of locally non-electroneutral incompressible
three-component matter is considered within the framework of general
relativity. For thermodynamic quantities like the pressure, the solution can be
represented as a series in the small parameter $1/\Lambda_{\mathrm G}\sim
10^{-36}$, where the first approximation is the well-known electroneutral
solution. However, the equilibrium equations for the chemical potentials of the
matter components, as it turns out, contain finite contributions from
non-electroneutrality effects even in the zeroth order. Analytical solutions
have been obtained for all of the parameters of the problem under
consideration, which are illustrated by numerical examples.
