TL;DR: Observations from multiple Earth-based observatories of Haumea passing in front of a distant star (a multi-chord stellar occultation) report the presence of a ring with an opacity of 0.5, which constrains the three-dimensional orientation of Haumesa and its triaxial shape, which is inconsistent with a homogeneous body in hydrostatic equilibrium.

TL;DR: In this paper, a central flash observed on 2015 June 29 is consistent with New Horizons REX profiles, provided that large diurnal temperature variations (not expected by current models) occur over Sputnik Planitia; and/or hazes with tangential optical depth of ~0.3 are present at 4-7 km altitude levels.

TL;DR: In this paper, the authors used data from five stellar occultations observed between 2013 and 2016 to constrain Chariklo's size and shape, and the ring reflectivity, using a Bayesian approach to estimate the corresponding parameters.

TL;DR: In this article, the authors used eleven stellar occultations by Pluto observed between 2002 and 2016 to retrieve atmospheric profiles (density, pressure, temperature) between $5 km and $380 km altitude levels (i.e. pressures from about 10 microbar to 10 nanobar).
