AI 中文摘要
我们通过联合求解托尔曼-奥本海默-沃尔科夫方程、哈特勒偶极方程及波斯特尼科夫-欣德雷方程,针对具有强度为ζ的李-黄-杨修正的多方状态方程,研究缓慢旋转的玻色-爱因斯坦凝聚(BEC)暗星。对ζ从0到1.5的连续扫描显示,平均场到修正的转变是平滑的,中间值处无隐藏结构。对基础玻色子参数(m,as)进行更广泛的扫描,我们发现,在该状态方程类中,2倍太阳质量的最大质量上限与类似GW170817的潮汐上限Λ₁.₄≲800无法同时满足。I-Love普适关系在12个(m,as,ζ)模型中的精度达0.13%,且ζ=0和ζ=1序列以一致的非随机偏移位于主曲线两侧。将同一求解器直接应用于真实核物质(SLy、APR4)时,其再现的最大质量与已发表结果的偏差在1%以内;应用于自束缚MIT袋夸克物质时,得到预期的质量-半径形态;当扩展为双流体重子加暗物质形式后,结果显示混合星的最大质量并非中心暗物质分数的单调函数。汇集核、混合及BEC暗星模型的I-Love序列,我们发现它们可坍缩至单一曲线,偏差约5%,而自束缚夸克星则远离该曲线,偏离高达90%。
英文摘要
We study slowly rotating Bose--Einstein condensate (BEC) dark stars by solving the Tolman--Oppenheimer--Volkoff, Hartle dipole, and Postnikov--Hinderer equations together for a polytropic equation of state with a Lee--Huang--Yang correction of strength $ζ$~\citep{Panotopoulos2026}. A continuous scan of $ζ$ from 0 to 1.5 shows the mean-field-to-corrected transition is smooth, with no hidden structure at intermediate values. Scanning the underlying boson parameters $(m,a_s)$ more broadly, we find that a $2\,M_\odot$ maximum-mass bound and a GW170817-like tidal bound $Λ_{1.4}\lesssim800$ cannot be satisfied simultaneously anywhere in this equation-of-state class. The $I$-Love universal relation holds to $0.13\%$ across twelve $(m,a_s,ζ)$ models, and the $ζ=0$ and $ζ=1$ sequences sit on opposite sides of the master curve by a consistent, non-random offset. Applied without modification to realistic nuclear matter (SLy, APR4), the same solver reproduces published maximum masses to within $1\%$; applied to self-bound MIT-bag quark matter it gives the expected mass--radius shape; and once extended to a two-fluid baryon-plus-dark-matter formalism, it shows that the maximum mass of a hybrid star is not a monotonic function of the central dark-matter fraction. Pooling $I$-Love sequences across nuclear, hybrid, and BEC dark-star models, we find they collapse onto a single curve to within about $5\%$, while self-bound quark stars sit far off it, departing by up to $90\%$.
