摘要
理论与模拟预测，强烈时空曲率接近黑洞会弯曲光线与物质的轨迹，从而在相对论扭矩作用下驱动盘和喷流的预cession。然而，关于盘-喷流共同预cession的直接观测证据仍然尚未确认。本文报告了目前为止最具说服力的案例：一次破裂星体事件（TDE）显示出前所未有的19.6天准周期性变化，同时在X射线和射电波段出现，其中X射线振幅超过一个数量级。几乎同步的X射线和射电变化表明存在一种统一的调制发射区域的机制。我们证明，盘-喷流Lenze-Thirring预cession模型成功再现了这些变化，但要求黑洞自转较小。本研究揭示了TDE中以前未知的短期射电波变动，凸显了高采样率射电监测的变革潜力，并为理解盘-喷流物理学提供了深刻见解。
