Abstract We have studied a new solution of charged gravastars with isotropic matter configuration in the framework of f(R, T) theory of gravity. For this purpose, we have assumed the electric charge as a constant. This stellar structure divided into three different regions: The preliminary part shows the interior charged region in which pressure equals to the negative density, second is the intermediate charged shell which is assumed to be very thin and filled with ultrarelativistic stiff fluid and the last corresponds to the electrovacuum region which is defined by an exterior Reissner-Nordstrom solution. Under these assumptions, we have found some physical aspects like length, energy, entropy and equation of state for charged spherical gravastar distribution. Moreover, we present an exact solution that free from event horizon and non-singular for this our new model.

电磁场对局部各向同性引力星稳定性的影响

摘要 我们在f(R, T)引力理论的框架下研究了具有各向同性物质构型的带电引力星的新解。为此，我们假设电荷为常数。这个恒星结构分为三个不同的区域：前半部分显示了内部带电区域，其中压力等于负密度，第二部分是中间带电壳，假设非常薄并充满超相对论刚性流体，最后部分对应于由外部 Reissner-Nordstrom 解定义的电真空区域。在这些假设下，我们发现了带电球形引力星分布的一些物理方面，如长度、能量、熵和状态方程。而且，
