1998 SM165: a large Kuiper belt object with an irregular shape.
The recent discovery of an ancient reservoir of icy bodies at and beyond the orbit of Neptune-the Kuiper belt-has opened a new frontier in astronomy. Measurements of the physical and chemical nature of Kuiper belt objects (KBOs) can constrain our ideas of the processes of planet formation and evolution. Our 1.8-m Vatican Advanced Technology Telescope and charge-coupled device camera observation...
متن کاملFrom Kuiper Belt Object to Cometary Nucleus
We now realise that many small body populations are related through a common origin in the Kuiper Belt, notably the Centaurs, the Jupiter Family Comets and certain dead-comets. But does primitive material from the Kuiper Belt survive the journey to the inner solar system and can we learn anything about it by studying the comets? We discuss observational evidence and other considerations that re...
متن کاملThe Chemical Composition of an Extrasolar Kuiper-Belt-Object
The Kuiper Belt of our solar system is a source of short-period comets that may have delivered water and other volatiles to Earth and the other terrestrial planets. However, the distribution of water and other volatiles in extrasolar planetary systems is largely unknown. We report the discovery of an accretion of a Kuiper-Belt-Object analog onto the atmosphere of the white dwarf WD 1425+540. Th...
متن کاملLarge Bodies in the Kuiper Belt
We present a survey for bright Kuiper Belt Objects (KBOs) and Centaurs, conducted at the Kitt Peak National Observatory (KPNO) 0.9 m telescope with the KPNO 8k Mosaic CCD. The survey imaged 164 sq deg near opposition to a limiting red magnitude of 21.1. Three bright KBOs and one Centaur were found, the brightest KBO having red magnitude 19.7, about 700 km in diameter assuming a dark Centaur-lik...
متن کاملOptical Spectroscopy of the Large Kuiper Belt
We present high signal precision optical reflectance spectra of the large Kuiper Belt objects 2005 FY9 and 2003 EL61. The spectrum of 2005 FY9 exhibits strong CH4 ice bands. A comparison between the spectrum and a Hapke model indicates that the CH4 bands are shifted 3:25 2:25 8 relative to pure CH4 ice, suggesting the presence of another ice component on the surface of 2005 FY9, possibly N2 ice...
