TL;DR: The observation of a multi-chord stellar occultation by Eris on 6 November 2010 is reported, consistent with a spherical shape for Eris, and it is anticipated that this atmosphere may periodically sublimate as Eris approaches its perihelion, at 37.8 astronomical units from the Sun.

TL;DR: The disappearances and reappearances of the star were abrupt, showing that Makemake has no global Pluto-like atmosphere at an upper limit of 4–12 nanobar (1σ) for the surface pressure, although a localized atmosphere is possible.

TL;DR: The Outer Solar System Origins Survey (OSSOS) as discussed by the authors was used to detect 838 trans-Neptunian objects (TNOs) with accurate known orbits, including 313 resonant TNOs and 132 plutinos.
Journal ArticleDOI

TL;DR: In this paper, the rotational lightcurve amplitude of Chiron was derived from observations at the 1.23 m CAHA telescope and indeed its amplitude is smaller than in 1988.
