Abstract: | We consider the static and spherically symmetric field equations of general relativity for charged perfect fluid spheres in
the presence of a cosmological constant. Following work by Florides (J Phys A Math Gen 16:1419–1433, 1983) we find new exact solutions of the field equations, and discuss their mass radius ratios. These solutions, for instance,
require the charged Nariai metric to be the vacuum part of the spacetime. We also find charged generalizations of the Einstein
static universe and speculate that the smallness problem of the cosmological constant might become less problematic if charge
is taken into account. |
