Abstract
We find a class of solutions to the Einstein-Maxwell system for a charged s phere with a particular choice of the electric field intensity by assuming a particular form for the hypersurfaces {t = constant}. In the uncharged li mit we regain static stars studied previously. A qualitative analysis of th e physical features of the model is performed. The presence of charge allow s for more general behaviour than is the case for uncharged spheres. In par ticular we show that the causal signals are permitted over a wider range of parameters in the presence of charge. Also we show that our solutions sati sfy a simple scaling relationship.
