Properties of the solar neighbor WISE J072003.20−084651.2

Valentin D. Ivanov, P. Väisänen, Alexei Y. Kniazev, Y. Beletsky et autres

Context. The severe crowding towards the Galactic plane suggests that the census of nearby stars in that direction may be incomplete. Recently, Scholz reported a new M9 object at an estimated distance d ≃ 7 pc (WISE J072003.20−084651.2; hereafter WISE J0720) at …

DE-BIASED POPULATIONS OF KUIPER BELT OBJECTS FROM THE DEEP ECLIPTIC SURVEY

Elisabeth R. Adams, Amanda A. S. Gulbis, J. L. Elliot, Susan Benecchi et autres

The Deep Ecliptic Survey (DES) was a survey project that discovered hundreds of Kuiper Belt objects from 1998 to 2005. Extensive follow-up observations of these bodies has yielded 304 objects with well-determined orbits and dynamical classifications into one of several categories: Classical, …
