Abstract

Within the framework of higher dimensions, we enhance the model of Pandya and Thomas and assume that the system is anisotropic in the Finch and Skea ansatz. Our model explores various physical parameters in higher dimensions, including mass, energy density, radial and transverse pressures, and the anisotropy factor. We have used graphical technique to analyse the energy conditions, equilibrium conditions, and stability across different dimensions. Furthermore, the mass of a particular compact object have shown to increase with radial parameter as space-time dimensions increase. Additionally, by generating a mass-radius (M-R) plot, we demonstrate the influence of dimensional factor on the maximum mass and radius allowed by our toy model.

改进的高维Finch和Skea恒星模型
在高维的框架内,我们对Pandya和Thomas的模型进行了改进,并在Finch和Skea中假设系统是各向异性的。我们的模型在更高的维度上探索了各种物理参数,包括质量、能量密度、径向和横向压力以及各向异性因素。我们使用图形技术分析了不同维度的能量条件、平衡条件和稳定性。此外,随着时空维度的增加,特定致密物体的质量随径向参数的增加而增加。此外,通过生成质量-半径(M-R)图,我们证明了尺寸因素对我们的玩具模型允许的最大质量和半径的影响。
