Occultations of Stars Brighter Than 15 mag by the Largest Trans-Neptunian Objects in 2004-2014
Abstract
We computed the occultations of stars brighter than 15 mag by the largest trans-Neptunian objects (TNOs) for the next ten years. In our search, we used the following catalogs: Hipparcos; Tycho2 with the coordinates of 2838666 stars taken from UCAC2 (Herald 2003); and UCAC2 (Zacharias et al. 2003) with 16356096 stars between 12.00 mag and 14.99 mag north of -45 ° declination. We predicted the occultations of stars by the seventeen largest numbered TNOs, the recently discovered 2004 DW, and four known binary Kuiper Belt objects. We selected 64 events at Solar elongations of no less than 30 °, including the extremely rare occultation of a 6.5 mag star by the double asteroid (66652) 1999 RZ253 on October 4, 2007. Observations of these events by all available means are extremely important, since they can provide unique information about the sizes of TNOs and improve our knowledge of their orbits dramatically.
