Generating solutions for charged stellar models in general relativity

It is shown that the expressions for tangential pressure, anisotropy factor and radial pressure in Einstein - Maxwell equations may serve as generating functions charged stellar models. The latter can incorporate an equation of state when expression energy density also used. Other are based on condition existence conformal motion (conformal flatness particular) Karmarkar embedding class one metrics, which do not depend charge. In all these cases linear first order differential metric components Riccati other. be always transformed into second homogenous equations. These conclusions illustrated by numerous particular examples from study
