论文摘要
HD106906是一个行星系统，具有宽大的伴侣，以及一个偏心和平坦的碎屑磁盘，对其形成和随后的演变构成了重要的约束。对伴侣的最新观察结果将其轨道限制为偏心且相对于碎屑盘的平面而言。在这里，我们表明，在倾向同伴的存在下，碎片盘很快（$ \ lyssim5 $ myr）变得扭曲和浮肿。这表明系统的当前配置相对较新。我们探讨了最近与自由浮动星球的紧密相遇可能会产生与HD106906B观察的轨道参数的同伴。我们发现，这种情况能够重新创建碎屑磁盘的结构，同时产生与观察一致的伴侣。
HD106906 is a planetary system that hosts a wide-orbit companion, as well as an eccentric and flat debris disk, which hold important constraints on its formation and subsequent evolution. The recent observations of the companion constrain its orbit to be eccentric and inclined relative to the plane of the debris disk. Here, we show that, in the presence of the inclined companion, the debris disk quickly ($\lesssim5$ Myr) becomes warped and puffy. This suggests that the current configuration of the system is relatively recent. We explore the possibility that a recent close encounter with a free floating planet could produce a companion with orbital parameters that agree with observations of HD106906b. We find that this scenario is able to recreate the structure of the debris disk while producing a companion in agreement with observation.
