Since the discovery of the first extrasolar giant planets around Sun-like stars, evolving observational capabilities have brought us closer to the detection of true Earth analogues…
Constraining the interior of extrasolar giant planets with the tidal Love number k_2 using the example of HAT-P-13b
U. Kramm, N. Nettelmann, J. J. Fortney +2
Transit and radial velocity observations continuously discover an increasing number of exoplanets. However, when it comes to the composition of the observed planets the data are co…

Characterizing the Cool KOIs II. The M Dwarf KOI-254 and its Hot Jupiter
John Asher Johnson, J. Zachary Gazak, Kevin Apps +12
We report the confirmation and characterization of a transiting gas giant planet orbiting the M dwarf KOI-254 every 2.455239 days, which was originally discovered by the Kepler mis…
Warm Spitzer Photometry of XO-4b, HAT-P-6b and HAT-P-8b
Kamen O. Todorov, Drake Deming, Heather A. Knutson +11
We have analyzed Warm Spitzer/IRAC observations of the secondary eclipses of three planets, XO-4b, HAT-P-6b and HAT-P-8b. We measure secondary eclipse amplitudes at 3.6μm and 4.5μm…
The Flat Transmission Spectrum of the Super-Earth GJ1214b from Wide Field Camera 3 on the Hubble Space Telescope
Zachory K. Berta, David Charbonneau, Jean-Michel Désert +7
Capitalizing on the observational advantage offered by its tiny M dwarf host, we present HST/WFC3 grism measurements of the transmission spectrum of the super-Earth exoplanet GJ121…
On the misalignment of the directly imaged planet β Pictoris b with the system's warped inner disk
Rebekah I. Dawson, Ruth A. Murray-Clay, Daniel C. Fabrycky
The vertical warp in the debris disk Beta Pictoris -- an inclined inner disk extending into a flat outer disk -- has long been interpreted as the signpost of a planet on an incline…
Astrometry and radial velocities of the planet host M dwarf GJ 317: new trigonometric distance, metallicity and upper limit to the mass of GJ 317b
Guillem Anglada-Escudé, Alan P. Boss, Alycia J. Weinberger +4
We have obtained precision astrometry of the planet hosting M dwarf GJ 317 in the framework of the Carnegie Astrometric Planet Search project. The new astrometric measurements give…
On the Migration of Jupiter and Saturn: Constraints from Linear Models of Secular Resonant Coupling with the Terrestrial Planets
Craig B. Agnor, D. N. C. Lin
We examine how the late divergent migration of Jupiter and Saturn may have perturbed the terrestrial planets. We identify six secular resonances between the nu_5 apsidal eigenfrequ…
The Optical and Near-Infrared Transmission Spectrum of the Super-Earth GJ1214b: Further Evidence for a Metal-Rich Atmosphere
Jacob L. Bean, Jean-Michel Désert, Petr Kabath +7
We present an investigation of the transmission spectrum of the 6.5 M_earth planet GJ1214b based on new ground-based observations of transits of the planet in the optical and near-…
Rapid Mid-Infrared Variability in Protostellar Disks
Te T. Ke, Hao Huang, Douglas N. C. Lin
Spectral energy distribution (SED) in protostellar disks is determined by the disks'internal dissipation and reprocessing of irradiation from their host stars. Around T Tauri stars…
Kepler 18-b, c, and d: A System Of Three Planets Confirmed by Transit Timing Variations, Lightcurve Validation, Spitzer Photometry and Radial Velocity Measurements
William D. Cochran, Daniel C. Fabrycky, Guillermo Torres +51
We report the detection of three transiting planets around a Sunlike star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satel…
A Search for the Transit of HD 168443b: Improved Orbital Parameters and Photometry
Genady Pilyavsky, Suvrath Mahadevan, Stephen R. Kane +13
The discovery of transiting planets around bright stars holds the potential to greatly enhance our understanding of planetary atmospheres. In this work we present the search for tr…
Spin-Orbit Alignment for the Circumbinary Planet Host Kepler-16A
Joshua N. Winn, Simon Albrecht, John Asher Johnson +31
Kepler-16 is an eccentric low-mass eclipsing binary with a circumbinary transiting planet. Here we investigate the angular momentum of the primary star, based on Kepler photometry…
Kepler-16: A Transiting Circumbinary Planet
Laurance R. Doyle, Joshua A. Carter, Daniel C. Fabrycky +46
We report the detection of a planet whose orbit surrounds a pair of low-mass stars. Data from the Kepler spacecraft reveal transits of the planet across both stars, in addition to…
Constraining High Speed Winds in Exoplanet Atmospheres Through Observations of Anomalous Doppler Shifts During Transit
Eliza Miller-Ricci Kempton, Emily Rauscher
Three-dimensional (3-D) dynamical models of hot Jupiter atmospheres predict very strong wind speeds. For tidally locked hot Jupiters, winds at high altitude in the planet's atmosph…
Discovery and Atmospheric Characterization of Giant Planet Kepler-12b: An Inflated Radius Outlier
Jonathan J. Fortney, Brice-Olivier Demory, Jean-Michel Desert +34
We report the discovery of planet Kepler-12b (KOI-20), which at 1.695\pm0.030 RJ is among the handful of planets with super-inflated radii above 1.65 RJ. Orbiting its slightly evol…
