论文摘要
我们讨论使用两流体的tolman-oppenheemer-volkov方程在强磁场的情况下与费米子暗物质混合的奇怪恒星。我们使用MIT袋型号描述了奇怪的夸克物质，并考虑范围内的磁场$ \ sim 10^{17} -10^{18} $G。对于费米米金暗物质，我们考虑了自由颗粒的情况，并且具有强烈的自我交互粒子，带有深色费米亚质量$ M = 5，100，100，500 $ GEV。我们讨论了暗物质和强磁场对恒星质量和半径的影响，以及其潮汐变形性。尽管强磁场有助于减少恒星的总质量，但它们通过增加混合系统中的暗物质分数带来的最大质量降低速率。然而，最受影响的最受影响的是潮汐变形，对于合理的磁场或暗物质中央能量密度的合理值，其范围为$ 70 \％-90 \％$。
We discuss strange stars admixed with fermionic dark matter in the presence of a strong magnetic field using the two-fluid Tolman-Oppenheimer-Volkov equations. We describe strange quark matter using the MIT bag model and consider magnetic fields in the range $\sim 10^{17}-10^{18}$ G. For the fermionic dark matter, we consider the cases of free particles and strongly self-interacting particles, with dark fermion masses $m=5, 100, 500$ GeV. We discuss the effects of dark matter and a strong magnetic field on the masses and radii of the stars, as well as on its tidal deformability. Even though strong magnetic fields contribute to decreasing the total mass of the star, they attenuate the rate of decrease in the maximum mass brought about by increasing the dark matter fraction in the admixed system. The most intensely affected observable, however, is the tidal deformability, with variations on the range of $70\%-90\%$ for reasonable values of the magnetic field or dark matter central energy density.
