High S/N Keck and Gemini AO imaging of Uranus during 2012-2014: New cloud patterns, increasing activity, and improved wind measurements
L. A. Sromovsky, I. de Pater, P. M. Fry +2
We imaged Uranus in the near infrared from 2012 into 2014, using the Keck/NIRC2 camera and Gemini/NIRI camera, both with adaptive optics. We obtained exceptional signal to noise ra…
The Kepler-454 System: A Small, Not-rocky Inner Planet, a Jovian World, and a Distant Companion
Sara Gettel, David Charbonneau, Courtney D. Dressing +47
Kepler-454 (KOI-273) is a relatively bright (V = 11.69 mag), Sun-like starthat hosts a transiting planet candidate in a 10.6 d orbit. From spectroscopy, we estimate the stellar tem…
Cometary Science with the James Webb Space Telescope
Michael S. P. Kelley, Charles E. Woodward, Dennis Bodewits +12
The James Webb Space Telescope (JWST), as the largest space-based astronomical observatory with near- and mid-infrared instrumentation, will elucidate many mysterious aspects of co…
Enceladus's measured physical libration requires a global subsurface ocean
P. C. Thomas, R. Tajeddine, M. S. Tiscareno +5
Several planetary satellites apparently have subsurface seas that are of great interest for, among other reasons, their possible habitability. The geologically diverse Saturnian sa…
Spitzer Secondary Eclipse Observations of Five Cool Gas Giant Planets and Empirical Trends in Cool Planet Emission Spectra
Joshua A. Kammer, Heather A. Knutson, Michael R. Line +15
In this work we present Spitzer 3.6 and 4.5 micron secondary eclipse observations of five new cool (<1200 K) transiting gas giant planets: HAT-P-19b, WASP-6b, WASP-10b, WASP-39b, a…
A Search for Subkilometer-sized Ordinary Chondrite Like Asteroids in the Main-Belt
H. W. Lin, Fumi Yoshida, Y. T. Chen +2
The size-dependent effects of asteroids on surface regolith and collisional lifetimes suggest that small asteroids are younger than large asteroids. In this study, we performed mul…
Discovery of a Disk Gap Candidate at 20 AU in TW Hydrae
E. Akiyama, T. Muto, N. Kusakabe +53
We present a new Subaru/HiCIAO high-contrast H-band polarized intensity (PI) image of a nearby transitional disk associated with TW Hydrae. The scattered light from the disk was de…
Uranus at equinox: Cloud morphology and dynamics
Lawrence Sromovsky, Patrick Fry, Heidi Hammel +5
As the 7 December 2007 equinox of Uranus approached, ring and atmosphere observers produced a substantial collection of observations using the 10-m Keck telescope and the Hubble Sp…
Post-equinox dynamics and polar cloud structure on Uranus
Lawrence Sromovsky, Patrick Fry, Heidi Hammel +2
Post equinox imaging of Uranus by HST, Keck, and Gemini telescopes has enabled new measurements of winds over previously sampled latitudes as well as measurements at high northern…
Methane depletion in both polar regions of Uranus inferred from HST/STIS and Keck/NIRC2 observations
Lawrence Sromovsky, Erich Karkoschka, Patrick Fry +3
From STIS observations of Uranus in 2012, we found that the methane volume mixing ratio declined from about 4% at low latitudes to about 2% at 60 deg N and beyond. This is similar…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
KOI-3158: The oldest known system of terrestrial-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. Whil…
An ancient extrasolar system with five sub-Earth-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
