摘要

台湾-美国掩星调查(TAOS)旨在探测柯伊伯带内外的小天体(直径约1公里)偶然掩星。这样的事件非常罕见(每颗恒星每年小于10−3次),持续时间也很短(约200毫秒),因此必须以高读数节奏监测许多恒星。TAOS在台湾中部的芦林天文台使用四个望远镜,以5赫兹的读出频率同时监测大约500颗恒星。在本文中,我们报告了在7年的数据中寻找柯伊伯带小天体(kbo)的结果。由于没有发现掩星事件,因此KBO大小分布的暗端斜率的95% c.l.上限为q = 3.34-3.82,这取决于直径约为90 km的大小分布中断处的表面密度。

The Taiwanese–American Occultation Survey (TAOS) aims to detect serendipitous occultations of stars by small (∼1 km diameter) objects in the Kuiper Belt and beyond. Such events are very rare (<10−3 events per star per year) and short in duration (∼200 ms), so many stars must be monitored at a high readout cadence. TAOS monitors typically ∼500 stars simultaneously at a 5 Hz readout cadence with four telescopes located at Lulin Observatory in central Taiwan. In this paper, we report the results of the search for small Kuiper Belt objects (KBOs) in seven years of data. No occultation events were found, resulting in a 95% c.l. upper limit on the slope of the faint end of the KBO size distribution of q = 3.34–3.82, depending on the surface density at the break in the size distribution at a diameter of about 90 km.
