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: Gil-hutton et al. as discussed by the authors presented a paper on the "Complejo Astronomico "El Leoncito", which was published by the Consejo Nacional de Investigaciones Cienti-ficas y Tecnicas (CICTE).

TL;DR: In this paper, an upper bound for the number of unseen small objects and the equivalent width of putative Pluto rings is provided. But this limit applies for narrow rings only, i.e. less than about 10 km in width.
