论文摘要
第一个已知的星际对象1i/2017 U1'Oumuamua表现出如此不寻常的特性，其起源仍然是许多辩论的主题。我们建议“ Oumuamua的特性”可以解释为在碎片外的云comet内部昏迷中形成的分形灰尘骨料（“灰尘兔子”）。这样的碎片可以通过积累灰尘颗粒来作为吸积位点，从而形成分形骨料。由于流体动力应激，分形骨料最终从碎片中脱离。这些彗星分形聚集体中的大多数都通过辐射压力驱逐到星际空间中。
The first known interstellar object, 1I/2017 U1 'Oumuamua, displayed such unusual properties that its origin remains a subject of much debate. We propose that 'Oumuamua's properties could be explained as those of a fractal dust aggregate (a "dust bunny") formed in the inner coma of a fragmenting exo-Oort cloud comet. Such fragments could serve as accretion sites by accumulating dust particles, resulting in the formation of a fractal aggregate. The fractal aggregate eventually breaks off from the fragment due to hydrodynamic stress. With their low density and tenuously bound orbits, most of these cometary fractal aggregates are then ejected into interstellar space by radiation pressure.
