Status of the Transneptunian Automated Occultation Survey(TAOS II)

摘要

The Transneptunian Automated Occultation Survey (TAOS II) will aim to detect 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 II will operate three 1.3 meter telescopes at the Observatorio Astronómico Nacional at San Pedro Mártir in Baja California, México. With a 2.3 square degree field of view and a high speed camera comprising CMOS imagers, the survey will monitor 10,000 stars simultaneously with all three telescopes at a readout cadence of 20 Hz. Construction of the site began in the fall of 2013, and the survey will begin in the summer of 2017.
