Compact stellar models in modified gravity
arXiv:2106.14645 · doi:10.1142/S0218271821400034
Abstract
In the present investigation compact stellar models are dealt with in the framework of the modified gravity theory, specifically of type. We have considered that the compact objects are following a spherically symmetric static metric and obtained the Einstein field equations in the spacetime of . To make the Einstein equations solvable we employ the methodology of conformal Killing vectors. Thereafter by using the MIT bag equation of state to the compact stars, considering that the stars are formed by strange quark, we find the solutions set. The solutions are examined via several physical tastings which exhibit viability of the model.
