The solutions split into two classes: a class of \"astro-physically interesting\" solutions describing \"ordinary\" matter with positive density and pressure, and a class of \"phantom-like\" solutions with positive density but negative active gravitational mass, which can also be of interest in several \"very strong fields\" regimes.
