This work is devoted to study the analytical and regular solutions of a particular self-gravitating object (i.e., gravastar) in a particular theory of gravity. We derive the corresponding field equations in the presence of effective energy momentum tensor associated with the perfect fluid configuration of a spherical system. We then describe the mathematical formulations of the three respective regions i.e., inner, shell and exterior of a gravastar separately. Additionally, the significance and physical characteristics along with the graphical representation of gravastars are discussed in detail. It is seen that under some specific constraints, $f(R,T,R_{\mu \nu }{T}^{\mu \nu })$ gravity is likely to host gravastars.

这项工作致力于研究特定引力理论中特定自重物体（例如，引力星）的解析解和正则解。我们在存在与球形系统的完美流体配置相关的有效能量动量张量的情况下，得出了相应的场方程。然后，我们分别描述了Gravastar的三个相应区域（即内部，外壳和外部）的数学公式。此外，详细讨论了引力星的重要性和物理特性以及图形表示。可以看出，在某些特定约束下，$F（\mathrm{[R}，Ť，{\mathrm{[R}}_{\mu \nu }{Ť}^{\mu \nu }）$ 引力很可能会吸引引力星。
