TL;DR: Observations at a variety of visible and infrared wavelengths of an occultation of a star by Pluto in August 2002 reveal evidence for extinction in Pluto's atmosphere and show that it has indeed changed, having expanded rather than collapsed, since 1988.

TL;DR: Observations of a multi-chord stellar occultation by KBO 55636, which occurred on 9 October 2009, find that it has a mean radius of 143 ± 5 km and a geometric albedo of in the V photometric band, which establishes that KBO55636 is smaller than previously thought and that, like its parent body, it is highly reflective.
Journal ArticleDOI
Changes in Pluto’s Atmosphere: 1988-2006

TL;DR: In this paper, a new modeling procedure is presented that allows a simultaneous fit of the atmospheric parameters for Pluto and the astrometric parameters for the occultation to all of the light curves.
Journal ArticleDOI
Global warming on Triton
James L. Elliot,James L. Elliot,Heidi B. Hammel,Lawrence H. Wasserman,Otto G. Franz,S. W. McDonald,Catherine B. Olkin,Edward W. Dunham,John R. Spencer,John Stansberry,Marc W. Buie,Jay M. Pasachoff,Bryce A. Babcock,T. H. McConnochie +13 more
TL;DR: In this paper, the authors reported observations of a recent stellar occultation by Triton which, when combined with earlier results, show that Tritón has undergone a period of global warming since 1989.
Journal ArticleDOI

TL;DR: Inversion of the MMT light curves with unprecedented signal-to-noise ratios reveals significant oscillations in the number density, pressure, and temperature profiles of Pluto's atmosphere as mentioned in this paper.
