摘要：
We present new exact solutions for the Einstein-Maxwell system in static spherically symmetric interior spacetimes. For a particular form of the gravitational potentials and the electric field intensity, it is possible to integrate the system in a closed form. For specific parameter values it is possible to find new exact models for the Einstein-Maxwell system in terms of elementary functions. Our model includes a particular charged solution found previously; this suggests that our generalized solution could be used to describe a relativistic compact sphere. A physical analysis indicates that the solutions describe realistic matter distributions. (C) 2009 Elsevier Ltd. All rights reserved.
