摘要
快速蓝色光学短暂现象 (FBOT) 是一种极具异常性的天体现象， 在X射线、光学和射电波段表现出异常强烈的辐射。其物理起源高度争议，已有多种解释， ranging 从恒星爆炸到星体破坏事件 (TDE)。本文报告了最亮FBOT之一——AT 2024wpp，其峰值后光度在X射线中重新点燃，并在光学中趋于平缓，其衰减率符合TDE特征（L_bol ∝ t^{-5/3}）。这暗示了来自中心致密天体的吸积能贡献，进一步得到X射线谱指数变硬以及在相近阶段检测到流出现象（从发射线推断）的支持。对光度演化的详细建模表明，AT 2024wpp最可能是由一颗34 M_sun的伍尔-莱特星与一颗15 M_sun黑洞 (BH) 的合并爆炸引起，这表明某些FBOT可能与恒星黑洞的星体破坏事件相关联。
