We investigate the f-mode oscillation of the dark matter admixed hyperon star within the relativistic Cowling approximation. The macroscopic properties are calculated with the relativistic mean-field equation of states by assuming that the dark matter particles are inside the star. The f-mode oscillation frequencies (only for l=2) are calculated with four different neutron star equation of states. We also check the effects of hyperons/dark matter and hyperons with dark matter equation of states on the f-mode oscillations varying with different astrophysical quantities such as mass (M), radius (R), compactness (M/R), surface red-shift (Zs), average density (ρ¯), and dimensionless tidal deformability (Λ) of the neutron star. Significant changes have been seen in the f-mode frequencies with and without hyperons/dark matter or hyperons+dark matter. Substantial correlations are observed between canonical frequencies and Λ (f1.4Λ1.4) and maximum frequencies and canonical Λ (fmaxΛ1.4).

暗物质对超子星f模式振荡的影响

我们调查 F- 暗物质混合超子星在相对论 Cowling 近似内的模式振荡。假设暗物质粒子在恒星内部,宏观性质是用相对论平均场状态方程计算的。这F-模式振荡频率(仅适用于 =2) 用四种不同的中子星状态方程计算。我们还用暗物质状态方程检查超子/暗物质和超子对F- 模式振荡随不同的天体物理量而变化,例如质量(), 半径 (电阻), 紧凑性 (/电阻), 表面红移 (Z), 平均密度 (ρ¯),和无量纲潮汐变形能力 (Λ) 的中子星。已经看到显着的变化F-带和不带超子/暗物质的模式频率或 超子+黑暗的事情。在规范频率和Λ (F1.4-Λ1.4) 和最大频率和规范 Λ (F最大限度-Λ1.4)。
