论文摘要
我们研究了参与双重紧凑型星星合并事件的恒星的性质，考虑了稳定的奇怪物质的相互作用模型。我们对该物质进行建模，使其与最近对紧凑型星质 - 拉迪乌斯和重力波事件的天体物理观察兼容。在这种情况下，我们考虑了有或没有自我互动的修改后的MIT袋型号和矢量袋模型。我们发现，$ 1.4〜m_ \ odot $奇异星的潮汐变形性上的新上限对应于从重力波事件中推断出的有效潮汐变形的上限。 $ 1.4〜m_ \ odot $ strange star的紧凑型范围作为$ {0.175} \ leq {c_ {1.4}} \ leq {0.199} $。半径范围为$ 15M_ \ odot $ priendar Star被推论为$ {10.57} \ leq {r_ {1.5}} \ leq {12.04} $ km，遵循严格的GW170817约束。 GW190425的约束提供了半径上限$ 1.7 $ $太阳质量奇怪的星星，其应小于$ 13.41 $ $ \ text {km} $。
We investigate the properties of stars participating in double compact star merger events considering interacting model of stable strange quark matter. We model the matter making it compatible with the recent astrophysical observations of compact star mass-radius and gravitational wave events. In this context we consider modified MIT bag model and vector bag model with and without self interaction. We find new upper bound on tidal deformability of $1.4~M_\odot$ strange star corresponding to the upper bound of effective tidal deformability inferred from gravitational wave event. Range of compactness of $1.4~M_\odot$ strange star is obtained as ${0.175}\leq{C_{1.4}}\leq{0.199}$. Radius range of $1.5M_\odot$ primary star is deduced to be ${10.57}\leq{R_{1.5}}\leq{12.04}$ km, following stringent GW170817 constraints. GW190425 constraints provide with upper limit on radius of $1.7$ solar mass strange star that it should be less than $13.41$ $\text{km}$.
