Millisecond time scales in the X-ray light curve of Scorpius X-1. The estimated sizes of these occulting TNOs are about or less than 100 m. This is the first time that TNOs of such a small size are detected. Our discovery of the X-ray occultation demonstrates a new method to study smaller TNOs.

所以，我们在这里介绍了我们利用X-ray波段的掩星方法，藉由利用RXTE卫星观测天蝎座X-1的数据，在毫秒尺度找到了一些可能的X-ray掩星事件，而这方法将可让我们了解一些大小在100公尺左右或更小的物体的分布情形，而这也是我们第一次在X-ray波段所发现掩星事件，而这方法的持续研究将能让我们对於太阳系的形成会有更多的帮助，因次在此提出来和大家分享。
