论文摘要
如我们所知，强磁场的作用会导致磁化紧凑物体的各向异性。因此，在本文中，我们研究了磁化中子恒星各向异性病例的结构特性。我们为两种形式的磁场，一种均匀和一个密度依赖性的磁场的中子恒星物质得出了状态（EOS）的方程。我们已经解决了广义的Tolman Oppenheimer Volkoff方程，以检查该系统的最大质量和相应的半径，Schwarzschild Radius，Graviatitication Redshift，Kretschmann Scalar和Buchdahl定理。结果表明，中子恒星的最大质量和半径正在增加磁场的功能。随着磁场的增加，红移，重力强度和kretschmann标量的增加。此外，已经研究了各向异性中子星的动力稳定性，最后与经验结果进行了比较。
As we know, the effect of strong magnetic field causes the anisotropy for the magnetized compact objects. Therefore, in this paper, we have studied the structure properties of anisotropic case of magnetized neutron star. We have derived the equation of state (EoS) of neutron star matter for two forms of magnetic fields, one uniform and one density dependent. We have solved the generalized Tolman Oppenheimer Volkoff equations to examine the maximum mass and corresponding radius, Schwarzschild radius, graviitational redshift, Kretschmann scalar, and Buchdahl theorem for this system. It was shown that the maximum mass and radius of neutron star are increasing functions of the magnetic field. Also redshift, strength of gravity, and Kretschmann scalar increase as the magnetic field increases. In addition, the dynamical stability of anisotrop neutron star has been investigated, and finally a comparison with the empirical results has been made.
