论文摘要
在本文中，我们考虑了一个双流体模型，假设脉冲星是由带有暗物质的普通物质制成的。暗物质的贡献来自星系sparc样品的旋转曲线的拟合[95]。为此，我们根据银河系晕区域的奇异等温球（SIS）暗物质密度曲线研究了暗物质。考虑到这种双流体模型，我们已经研究了不同星系中存在的脉冲星的物理特征。在这里，我们计算了四个脉冲星的可能的半径，紧凑度（U）和表面红移（ZS），即：NGC 6440B Galaxy中的PSR J1748-2021B，PSR J1911-5958A，NGC 6752 Galaxy，PSR B1802-6537 ngcy and ngc 6752 in ngc 6752在NGC 6441 Galaxy中。
In this paper, we have considered a twofluid model assuming that the pulsars are made of ordinary matter admixed with dark matter.Contribution of dark matter comes from the fitting of the rotation curves of the SPARC sample of galaxies[95]. For this we have investigated the dark matter based on the Singular Isothermal Sphere (SIS) dark matter density profile in the galactic halo region. Considering this twofluid model, we have studied the physical features of the pulsars present in different galaxy in details. Here, we compute the probable radii, compactness (u) and surface red-shift (Zs) of the four pulsars namely : PSR J1748-2021B in NGC 6440B galaxy, PSR J1911-5958A in NGC 6752 galaxy, PSR B1802-07 in NGC 6539 galaxy and PSR J1750-37A in NGC 6441 galaxy.
