TL;DR: Observations of a multichord stellar occultation revealed the presence of a ring system around (10199) Chariklo, which is a Centaur—that is, one of a class of small objects orbiting primarily between Jupiter and Neptune—with an equivalent radius of 124 9 kilometres.

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: Data from the first occultations by Pluto since 1988 are reported and it is found that, during the intervening 14 years, there seems to have been a doubling of the atmospheric pressure, a probable seasonal effect on Pluto.

TL;DR: Braga Ribas et al. as discussed by the authors proposed a method to improve the quality of the data collected by the data collection system of the government of Brazil, using data from the Ministerio de Ciencia, Tecnologia e Innovacao.
