In this paper, we analyze a few physical characteristics of gravastar with cylindrical geometry in f(R,T) theory, where R is the Ricci scalar and T is the trace of energy-momentum tensor. The gravastar is generally considered to be a substitute of a black hole with three different regions. In this work, we examine the formulation of gravastar-like cylindrical structures in f(R,T) theory. By using Darmois and Israel matching conditions, we formulate a mass function of a thin shell. We calculate the different physical characteristics of gravastar, in particular, entropy within the thin shell, proper length of the intermediate thin shell as well as energy of the shell.

修正重力下圆柱重力星的形成

在本文中，我们分析了具有圆柱几何形状的 gravastar 的一些物理特性。F(R,吨)理论，其中R是 Ricci 标量和吨是能量-动量张量的迹。重力星通常被认为是具有三个不同区域的黑洞的替代品。在这项工作中，我们研究了在F(R,吨)理论。通过使用 Darmois 和 Israel 匹配条件，我们制定了薄壳的质量函数。我们计算了gravastar的不同物理特性，特别是薄壳内的熵、中间薄壳的适当长度以及壳的能量。
