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: 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.

TL;DR: Observations from a multi-station stellar occultation by Charon are reported, which are used to derive the radius of Pluto and Charon, RC = 603.6 ± 1.4 km (1σ), and the density of ρ = 1.71 ± 0.08 g cm-3.3 (3σ) nanobar, assuming respectively a pure nitrogen or pure methane atmosphere.

TL;DR: In this paper, the authors present evidence that four minor planets of the main belt are binary systems based on CCD photometric measurements made by many observers coordinated in a network of observatories.

TL;DR: In this paper, the results of two multichord stellar occultations by the dwarf planet (1) Ceres that were observed from Brazil on 2010 August 17, and from the USA on 2013 October 25 were reported.
