Simultaneous Linear and Circular Optical Polarimetry of Asteroid (4) Vesta
Sloane J. Wiktorowicz, Larissa A. Nofi
From a single, 3.8-hour observation of asteroid (4) Vesta at phase angle with the POLISH2 polarimeter at the Lick Observatory Shane 3-m telescope, we confirm rotationa…
An Exploration of Double Diffusive Convection in Jupiter as a Result of Hydrogen-Helium Phase Separation
N. Nettelmann, J. J. Fortney, K. Moore +1
Jupiter's atmosphere has been observed to be depleted in helium (Yatm~0.24), suggesting active helium sedimentation in the interior. This is accounted for in standard Jupiter struc…
Detection of the secondary eclipse of WASP-10b in the Ks-band
Patricia Cruz, David Barrado, Jorge Lillo-Box +5
WASP-10b, a non-inflated hot Jupiter, was discovered around a K-dwarf in a near circular orbit (). Since its discovery in 2009, different published parameters for this…
The LEECH Exoplanet Imaging Survey. Further constraints on the planet architecture of the HR 8799 system
A. -L. Maire, A. J. Skemer, P. M. Hinz +36
Context. Astrometric monitoring of directly-imaged exoplanets allows the study of their orbital parameters and system architectures. Because most directly-imaged planets have long…
Ab initio equations of state for hydrogen (H-REOS.3) and helium (He-REOS.3) and their implications for the interior of Brown Dwarfs
Andreas Becker, Winfried Lorenzen, Jonathan J. Fortney +3
We present new equations of state (EOS) for hydrogen and helium covering a wide range of temperatures from 60 K to 10 K and densities from g/cm to g/cm$^3…
HST Rotational Spectral Mapping of Two L-Type Brown Dwarfs: Variability In and Out of Water Bands Indicates High-Altitude Haze Layers
Hao Yang, Daniel Apai, Mark S. Marley +13
We present time-resolved near-infrared spectroscopy of two L5 dwarfs, 2MASS J18212815+1414010 and 2MASS J15074759-1627386, observed with the Wide Field Camera 3 instrument on the H…
Migration and Growth of Protoplanetary Embryos I: Convergence of Embryos in Protoplanetary Disks
Xiaojia Zhang, Beibei Liu, Douglas N. C. Lin +1
According to the core-accretion scenario, planets form in protostellar disks through the condensation of dust, coagulation of planetesimals, and emergence of protoplanetary embryos…
Spitzer Secondary Eclipses of the Dense, Modestly-irradiated, Giant Exoplanet HAT-P-20b Using Pixel-Level Decorrelation
Drake Deming, Heather Knutson, Joshua Kammer +13
HAT-P-20b is a giant exoplanet that orbits a metal-rich star. The planet itself has a high total density, suggesting that it may also have a high metallicity in its atmosphere. We…
Migration and Growth of Protoplanetary Embryos II: Emergence of Proto-Gas-Giants Cores versus Super Earths' Progenitor
Beibei Liu, Xiaojia Zhang, Douglas N. C. Lin +1
Nearly of solar type stars contain one or more gas giant planet. According to the core-accretion scenario, the acquisition of their gaseous envelope must be preceded by th…
HST hot-Jupiter transmission spectral survey: detection of potassium in WASP-31b along with a cloud deck and Rayleigh scattering
D. K. Sing, H. R. Wakeford, A. P. Showman +15
We present Hubble Space Telescope optical and near-IR transmission spectra of the transiting hot-Jupiter WASP-31b. The spectrum covers 0.3-1.7 m at a resolution 70, which…
Embryo impacts and gas giant mergers II: Diversity of Hot Jupiters' internal structure
Shang-Fei Liu, Craig B. Agnor, D. N. C. Lin +1
We consider the origin of compact, short-period, Jupiter-mass planets. We propose that their diverse structure is caused by giant impacts of embryos and super-Earths or mergers wit…
Near-infrared Thermal Emission Detections of a number of hot Jupiters and the Systematics of Ground-based Near-infrared Photometry
Bryce Croll, Loic Albert, Ray Jayawardhana +7
We present detections of the near-infrared thermal emission of three hot Jupiters and one brown-dwarf using the Wide-field Infrared Camera (WIRCam) on the Canada-France-Hawaii Tele…
Accretion and differentiation of the terrestrial planets with implications for the compositions of early-formed Solar System bodies and accretion of water
David C. Rubie, Seth A. Jacobson, Alessandro Morbidelli +5
In order to test planetary accretion and differentiation scenarios, we integrated a multistage core-mantle differentiation model with N-body accretion simulations. Impacts between…
A Precise Water Abundance Measurement for the Hot Jupiter WASP-43b
Laura Kreidberg, Jacob L. Bean, Jean-Michel Désert +13
The water abundance in a planetary atmosphere provides a key constraint on the planet's primordial origins because water ice is expected to play an important role in the core accre…
Thermal structure of an exoplanet atmosphere from phase-resolved emission spectroscopy
Kevin B. Stevenson, Jean-Michel Desert, Michael R. Line +13
Exoplanets that orbit close to their host stars are much more highly irradiated than their Solar System counterparts. Understanding the thermal structures and appearances of these…
Characterization of the atmosphere of the hot Jupiter HAT-P-32Ab and the M-dwarf companion HAT-P-32B
Ming Zhao, Joseph G. O'Rourke, Jason T. Wright +13
We report secondary eclipse photometry of the hot Jupiter HAT-P-32Ab, taken with Hale/WIRC in H and Ks bands and with Spitzer/IRAC at 3.6 and 4.5 micron. We carried out adaptive op…
The Atmospheric Circulation of the Hot Jupiter WASP-43b: Comparing Three-Dimensional Models to Spectrophotometric Data
Tiffany Kataria, Adam P. Showman, Jonathan J. Fortney +5
The hot Jupiter WASP-43b has now joined the ranks of transiting hot Jupiters HD 189733b and HD 209458b as an exoplanet with a large array of observational constraints on its atmosp…
Constraining the Oblateness of Kepler Planets
Wei Zhu, Chelsea Huang, George Zhou +1
We use Kepler short cadence light curves to constrain the oblateness of planet candidates in the Kepler sample. The transits of rapidly rotating planets that are deformed in shape…
