带毛黑洞（BHs）以非平凡标量场或物质场为特征，除质量、电荷和自旋外引入了额外自由度，为检验偏离克尔范式的情况提供了框架。我们研究了一类在引力解耦框架内构建的旋转带毛黑洞，其时空满足带有守恒能量-动量张量的爱因斯坦场方程，且该张量符合强能量条件。在我们此前的工作（论文I；Dasgupta等人，2026）中，我们研究了这类黑洞的视界结构与测试粒子动力学，并将两种运动学高频准周期振荡（HFQPO）模型与六个黑洞源的观测结果进行了比对。基于该分析，我们在此将九种共振模型与相同的HFQPO数据进行比对，从而在带毛克尔框架内对十一种模型（两种运动学模型和九种共振模型）进行系统比较。基于两种运动学模型（论文I）和九种共振模型的综合分析显示，当前精度水平下的HFQPO数据无法排除带毛克尔情景。通过实施赤池信息准则，并检验推断出的自旋与此前独立自旋估计值的一致性，我们的分析为评估每个源的不同HFQPO模型的相对性能提供了系统框架。这些结果凸显了HFQPO在探测黑洞毛发方面的潜力，以及开展更精确观测、更好理解QPO物理起源的必要性。
英文摘要
Hairy black holes (BHs), characterized by nontrivial scalar or matter fields, introduce additional degrees of freedom beyond mass, charge, and spin, providing a framework for testing deviations from the Kerr paradigm. We investigate a class of rotating hairy black holes constructed within the gravitational decoupling framework, whose spacetime satisfies the Einstein field equations with a conserved energy-momentum tensor consistent with the strong energy conditions. In our previous work (Paper I; Dasgupta et al. 2026), we studied their horizon structure and test-particle dynamics and confronted two kinematic high-frequency quasi-periodic oscillation (HFQPO) models with observations of six black hole sources. Building on that analysis, we here test nine resonance models against the same HFQPO data, enabling a systematic comparison of eleven models (two kinematic and nine resonance) within the hairy Kerr framework. A comprehensive analysis based on the two kinematic models (Paper I) and the nine resonance models reveals that the HFQPO data with the current level of precision cannot rule out the hairy Kerr scenario. By implementing the Akaike Information Criterion and by examining the consistency of the inferred spins with previous independent spin estimates, our analysis provides a systematic framework for assessing the relative performance of different HFQPO models for each source. These results highlight the potential of HFQPOs to probe black hole hair and the need for more precise observations and a better understanding of the physical origin of QPOs.
