论文摘要
在本文中，我们获得了一些球形恒星构型，这些配置代表了黑暗能量星的新模型，这些恒星指定了特定形式的重力电势和电场强度，允许求解Einstein-Maxwell场方程。我们选择了Finch和Skea（1989）提出的度量潜力。我们发现径向压力，各向异性因子，能量密度，度量系数，质量功能，电荷密度是规则的，并且在恒星内部行为良好，但不满足因果关系和强大的能量。这些模型在物理和宇宙学中具有很大的应用，因为几个独立的观察结果表明宇宙处于加速膨胀阶段，这可以通过未检测到的暗能量的存在来解释
In this paper we obtained some spherically stellar configurations that represent new models of dark energy stars specifying particular forms for gravitational potential and the electric field intensity which allows solve the Einstein-Maxwell field equations. We have chosen the metric potential proposed by Finch and Skea (1989). We found that the radial pressure, the anisotropy factor, energy density, metric coefficients, mass function, charge density are regular and well behaved in the stellar interior but the causality conditions and of strong energy are not satisfied. These models have great application in physics and cosmology due to the fact that several independent observations indicate that the universe is in a phase of accelerated expansion which can be explained by the presence of dark energy that has not been detected
