TL;DR: In this paper, the authors used 12 successful occulations by Chariklo observed between 2014 and 2016 to provide ring profiles (physical width, opacity, edge structure) and constraints on the radii and pole position.

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 article, the authors present results from a multi-chord Pluto stellar occultation observed on 2015 June 29 from New Zealand and Australia, which occurred only two weeks before the NASA New Horizons flyby of the Pluto system and serves as a useful comparison between ground-based and space results.
