Abstract

The article examines the matter of gravitational vacuum stars, or gravastars, in the context of f(R,G,T) gravity, where R, G and T refer the Ricci Scalar, Gauss-Bonnet invariant term and Trace of energy momentum tensor. Here, using certain suitable numerical approaches, solutions to the highly nonlinear differential equations are determined. For a well-known f( R,G,T) gravity cosmological model, the main structure of gravastars has been discussed according to core, shell, and external region. It is illustrated graphically how the relationship between mass and radius has evolved for the gravastar under consideration.

f (R,G,T) 重力中的重力星

文章在f(R,G,T)引力的背景下研究了引力真空星（或称引力星）的问题，其中R、G和T指的是利玛窦标量、高斯-波奈不变项和能量动量张量的痕量。在这里，利用某些合适的数值方法，可以确定高度非线性微分方程的解。针对著名的 f( R,G,T) 引力宇宙学模型，按照核心、外壳和外部区域讨论了引力星的主要结构。图解说明了质量与半径之间的关系是如何在所考虑的引力星中演变的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
