论文摘要
在过去的几十年中，停血被认为是黑洞的严重替代品。除了标准的一般相对论（GR）以外，许多交替的重力模型已经构建了稳定的Grastar模型。 Randall-Sundrum（RS）Braneworld模型一直是GR的流行替代品，特别是在宇宙学和天体物理环境中。在这里，我们考虑了RS Brane Gravity中的GARVASTAR模型。与匹配条件的计算，已经获得了不同区域的数学解。已经计算并绘制了壳的各种重要物理参数，以查看它们的径向距离变化。我们还计算并绘制了表面红移，以检查RS Brane Gravity范围内的GRAVASTAR的稳定性。
Gravastars have been considered as a serious alternative to black holes in the past couple of decades. Stable models of gravastar have been constructed in many of the alternate gravity models besides standard General Relativity (GR). The Randall-Sundrum (RS) braneworld model has been a popular alternative to GR, specially in the cosmological and astrophysical context. Here we consider a gravastar model in RS brane gravity. The mathematical solutions in different regions have been obtained along with calculation of matching conditions. Various important physical parameters for the shell have been calculated and plotted to see their variation with radial distance. We also calculate and plot the surface redshift to check the stability of the gravastar within the purview of RS brane gravity.
