摘要：

New spherically symmetric gravastar solutions, stable to radial perturbations, are found by utilizing the construction of Visser and Wiltshire. The solutions possess an anti-de Sitter or de Sitter interior and a Schwarzschild-(anti)-de Sitter or Reissner-Nordstrom exterior. We find a wide range of parameters which allow stable gravastar solutions, and present the different qualitative behaviour of the equation of state for these parameters.
