Detection of Daily Clouds on Titan
TL;DR: It is proposed that Titan's atmosphere resembles Earth's, with clouds, rain, and an active weather cycle, driven by latent heat release from the primary condensible species.
Unusual Features of the 1--4 Micron Spectrum of HR 4049
TL;DR: In this article, moderate resolution spectra from 1.05 to 3.65 microns of the post-AGN star HR 4049 show a number of features indicative of intense mass loss and unusual circumstellar chemistry, including deep Brackett series absorption lines to rather high n states, emission in the 3.40 microns 'dust' features, and rarely occurring emission features near 3.5 microns.

TL;DR: In this paper , the authors carried out a multi-wavelength study of the jets, their driving sources, and the cloud core hosting the embedded stellar system, based on data from the Hubble Space Telescope, Gemini, Subaru, Apache Point Observatory 3.5 m, Karl G. Jansky Very Large Array, and Atacama Large Millimeter/submillimeter Array (ALMA) telescopes.
Ices on the Surface of Triton
Dale P. Cruikshank,Ted L. Roush,Tobias Owen,Thomas R. Geballe,Catherine de Bergh,Bernard Schmitt,Robert H. Brown,Mary Jane Bartholomew +7 more
TL;DR: The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component, which challenges existing models of methane and nitrogen photochemistry on Tritons.
Infrared Observations and Modeling of One of the Coolest T Dwarfs: Gliese 570D
Thomas R. Geballe,Didier Saumon,S. K. Leggett,Gillian R. Knapp,Mark S. Marley,Katharina Lodders +5 more
TL;DR: The authors obtained a good-quality R ~ 400, 0.8-2.5?m spectrum as well as accurate photometry of Gliese 570D, one of the coolest and least-luminous brown dwarfs currently known.
