论文摘要

此处介绍了一种基于Durgapal IV度量公制(Durgapal 1982)的新的奇怪星模模型。在这里,我们应用了一种特定方法来研究紧凑型物体的内部物理特性4U 1702-429,2A 1822-371,PSR J1756-2251,PSR J1802-2124和PSR J11713+047。 ($ρ_{0} $),表面密度($ρ_{b} $),中央压力($ p_ {0} $),Surface Redshift($ z_ {s} $),紧凑型和半径。此外,我们执行不同的测试来研究模型的稳定性,最后我们能够基于压力和密度,即可能的状态方程(EOS)给出一个方程,该方程在天体物理学领域具有重要意义。

A new strange star model based on Durgapal IV metric (Durgapal 1982) is presented here.Here we have applied a specific method to study the inner physical properties of the compact objects 4U 1702-429, 2A 1822-371, PSR J1756-2251,PSR J1802-2124 and PSR J1713+0747.The main objective of our study is to determine central density ($ρ_{0}$), surface density ($ρ_{b}$), central pressure ($p_{0}$), surface redshift ($Z_{s}$), compactness and radius. Further we perform different tests to study the stability of our model and finally we are able to give an equation based on pressure and density i.e probable equation of state (EoS) which has an important significances in the field of Astrophysics.
