来自潮汐破坏事件形成的预旋动超欧德星盘的多样辐射模式

潮汐破坏事件（TDE）发生在恒星穿过超大质量黑洞（SMBH）的潮汐半径内的情况。 在 TDEs 中，预期该破坏恒星的轨道角动量通常与 SMBH 自转轴错位，这应导致与 SMBH 自旋轴周围预旋的超欧德星盘。本文通过对之前的超欧德星盘模拟进行辐射传输计算，探讨此类 TDE 星盘产生的不同观察特征。我们展示了星盘和风的预旋导致 X 射线辐射的时间依赖性遮蔽和再加工。 Depending on the orientation of the viewing angle of the observer and the tilt angle of the disk, four main types of variability are induced: 1) The smooth-TDEs: The emissions from these TDEs show no fluctuations; 2) The dimmer: The main emission type (X-ray or optical) stays the same, with small to moderate modulations of brightness; 3) The blinker: X-ray and optical emissions take turns to dominate in one cycle of precession, with dramatic changes in the X-ray fluxes. 4) The siren: X-ray and optical emissions take over each other twice per cycle, possibly with two different peak X-ray fluxes within one cycle. In all three scenarios, we observe an inverse correlation between X-ray and optical emissions. Our model provides a physical framework for interpreting TDE multi-wavelength variability through disk precession dynamics and gives an alternative interpretation to the interesting case of J045650.3-203750 which was suggested to be a repeated partial TDE previously.
