AI 中文摘要
我们研究了包含反K介子凝聚、超子和Δ(1232)重子的冷的、非旋转中子星的核心成分g1模式，并据我们所知首次在完全广义相对论中计算了具有K−凝聚的恒星的连续成分g1模式频率和引力波阻尼时间。使用BigApple相对论平均场状态方程，我们计算了频率、阻尼时间和冻结成分潮汐重叠，并通过模式频率敏感性验证的物种分辨勒杜分解确定了浮力通道。我们将完全冻结物质与n↔p + K−的快速K极限和Δ四重奏的强平衡极限进行比较。快速K平衡保留了36% - 44%的峰值局部K介子浮力和65.7% - 73.4%的冻结终端配置频率，同时将阻尼时间增加了14.4 - 31.8倍；模式仍高于核子带。强Δ平衡消除了大部分直接的Δ诱导增强，使NΔ模式回到核子带，而高频NYΔ分支通过冻结的Λ梯度幸存下来。本征函数跟踪确认了连续的g1分支，代表性的DD - ME2计算重现了这种层次结构。直接的全广义相对论冻结成分相移满足|ΔΦg1|≤1.410×10−3 rad，比爱因斯坦望远镜的0.03 - rad有利事件尺度低21倍。因此，只有当外来物种的成分梯度或耦合的缓慢平衡梯度在振荡周期内幸存时，它才会产生独特的成分模式。
英文摘要
We study core composition \(g_1\) modes of cold, nonrotating neutron stars containing antikaon condensates, hyperons, and \(Δ(1232)\) baryons and present, to our knowledge, the first calculation in full general relativity of the continuous-composition \(g_1\)-mode frequency and gravitational-wave damping time for stars with a \(K^-\) condensate. Using the BigApple relativistic mean-field equation of state, we compute frequencies, damping times, and frozen-composition tidal overlaps, and identify the buoyancy channels with a species-resolved Ledoux decomposition validated by mode-frequency sensitivities. We compare fully frozen matter with a fast-\(K\) limit for \(n\leftrightarrow p+K^-\) and a strong-equilibrium limit for the \(Δ\) quartet. Fast-\(K\) equilibration retains \(36\%\)--\(44\%\) of the peak local kaon buoyancy and \(65.7\%\)--\(73.4\%\) of the frozen terminal-configuration frequencies, while increasing the damping times by factors of \(14.4\)--\(31.8\); the mode remains above the nucleonic band. Strong \(Δ\) equilibration removes most of the direct \(Δ\)-induced enhancement, returning the \(NΔ\) mode toward the nucleonic band, whereas the high-frequency \(NYΔ\) branch survives through the frozen \(Λ\) gradient. Eigenfunction tracking confirms a continuous \(g_1\) branch, and representative DD-ME2 calculations reproduce this hierarchy. The direct full-GR frozen-composition phase shifts satisfy \(|ΔΦ_{g_1}|\leq1.410\times10^{-3}\) rad, a factor of 21 below the \(0.03\)-rad favorable-event scale for the Einstein Telescope. An exotic species therefore produces a distinct composition mode only if its composition gradient, or a coupled slowly equilibrating gradient, survives over the oscillation period.
