TL;DR: The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes.
Journal ArticleDOI
A systematic retrieval analysis of secondary eclipse spectra. i. a comparison of atmospheric retrieval techniques
Michael R. Line,Aaron S. Wolf,Xi Zhang,Heather A. Knutson,Joshua A. Kammer,Elias Ellison,Pieter Deroo,D. Crisp,Yuk L. Yung +8 more
TL;DR: In this paper, the authors compare three spectral retrieval methods: optimal estimation, differential evolution Markov chain Monte Carlo, and bootstrap Monte Carlo on a synthetic water-dominated hot Jupiter and find that the three approaches agree for high spectral resolution, high signal-to-noise data expected to come from potential future spaceborne missions, but disagree for low-resolution, low signal tonoise spectra representative of current observations.
Journal ArticleDOI
Spitzer Secondary Eclipses of the Dense, Modestly-irradiated, Giant Exoplanet HAT-P-20b Using Pixel-Level Decorrelation
Drake Deming,Drake Deming,Heather A. Knutson,Joshua A. Kammer,Benjamin J. Fulton,James G. Ingalls,Sean Carey,Adam Burrows,Jonathan J. Fortney,Kamen O. Todorov,Eric Agol,Eric Agol,Nicolas B. Cowan,Jean-Michel Desert,Jonathan Fraine,Jonathan Langton,Caroline V. Morley,Adam P. Showman +17 more
TL;DR: In this article, a pixel-level decorrelation (PLD) method was proposed to correct the intra-pixel effect for Warm Spitzer data, which can significantly reduce or eliminate red noise in Spitzer secondary eclipse photometry even for eclipses that have proven to be intractable using other methods.
Journal ArticleDOI

TL;DR: Moore et al. as discussed by the authors presented the complex surface features and geology of Pluto and its large moon Charon, including evidence of tectonics, glacial flow, and possible cryovolcanoes.
Journal ArticleDOI

TL;DR: In this article, the authors analyzed a combined Hubble/Spitzer Space Telescope dataset of 12 transits and 20 eclipses of the sub-Neptune exoplanet GJ 3470 b, whose mass of 12.6
