Abstract:	摘要： We present observations of the recently discovered comet-like main-belt object P/2010 R2 (La Sagra) obtained by Pan-STARRS1 and the Faulkes Telescope-North on Haleakala in Hawaii, the University of Hawaii 2.2m, Gemini-North, and Keck I telescopes on Mauna Kea, the Danish 1.54 m telescope at La Silla, and the Isaac Newton Telescope on La Palma. An anti-solar dust tail is observed to be present from 2010 August through 2011 February, while a dust trail aligned with the object's orbit plane is also observed from 2010 December through 2011 August. The results strongly suggest that the observed activity is cometary in nature (i.e., driven by the sublimation of volatile material), and that P/La Sagra is therefore the most recent main-belt comet to be discovered. 出版者： United States 出版日期： 2012-05-01 出處： The Astronomical journal, 2012-05, Vol.143 (5), p.104-16 資源來源： Institute of Physics Journals 識別號： ISSN: 0004-6256 識別號： ISSN: 1538-3881 識別號： EISSN: 1538-3881 識別號： DOI: 10.1088/0004-6256/143/5/104
