论文摘要
目前的论文涉及$ f（r）$重力框架下紧凑型天体物理体的组成和建模。该模型用于各种观察到的奇怪恒星，即SMC X-1，SAX J1808.4-3658，Swift J1818.0-1607，PSR J1614-2230和PSR J0348+0432。在设置无量纲耦合参数$λ$的适当值后，将获得物理参数，例如密度，径向和切向压力。 Mass-Radius的关系而不假设任何状态方程式都足以容纳所有奇怪的恒星，几乎太阳能质量为2.5。检查了所有上述恒星的物理生存力，并发现满足所有规律性和稳定性条件。
Present paper deals with the composition and modelling of compact dense astrophysical bodies under the framework of $f(R)$ gravity. The model is employed on various observed strange stars viz., SMC X-1, SAX J1808.4-3658, Swift J1818.0-1607, PSR J1614-2230 and PSR J0348+0432. Upon setting the appropriate value of dimensionless coupling parameter $λ$, the physical parameters such as the density, the radial and tangential pressures were obtained. Mass-Radius relation without presuming any equation of state is capable enough to accommodate all strange stars nearly having solar mass up to 2.5. The physical viability of the model is examined for all the aforementioned stars and it is found that all the regularity and stability conditions are satisfied.
