Phase Curves of Hot Neptune LTT 9779b Suggest a High-Metallicity Atmosphere
Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan +20
Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements…
A TESS Dress Rehearsal: Planetary Candidates and Variables from K2 Campaign 17
Ian J. M. Crossfield, Natalia Guerrero, Trevor David +38
We produce light curves for all ~34,000 targets observed with K2 in Campaign 17 (C17), identifying 34 planet candidates, 184 eclipsing binaries, and 222 other periodic variables. T…
K2-66b and K2-106b: Two extremely hot sub-Neptune-size planets with high densities
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +20
We report precise mass and density measurements of two extremely hot sub-Neptune-size planets from the K2 mission using radial velocities, K2 photometry, and adaptive optics imagin…
Mass Constraints of the WASP-47 Planetary System from Radial Velocities
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +19
We report precise radial velocity (RV) measurements of WASP-47, a G star that hosts three transiting planets in close proximity (a hot Jupiter, a super-Earth and a Neptune-sized pl…
Hubble Space Telescope search for the transit of the Earth-mass exoplanet Alpha Centauri Bb
Brice-Olivier Demory, David Ehrenreich, Didier Queloz +13
Results from exoplanet surveys indicate that small planets (super-Earth size and below) are abundant in our Galaxy. However, little is known about their interiors and atmospheres.…
Spitzer Transits of the Super-Earth GJ1214b and Implications for Its Atmosphere
Jonathan D. Fraine, Drake Deming, Michaël Gillon +7
We observed the transiting super-Earth exoplanet GJ1214b using Warm Spitzer at 4.5 microns wavelength during a 20-day quasi-continuous sequence in May 2011. The goals of our long o…
Mission to the Trojan Asteroids: lessons learned during a JPL Planetary Science Summer School mission design exercise
Serina Diniega, Kunio M. Sayanagi, Jeffrey Balcerski +16
The 2013 Planetary Science Decadal Survey identified a detailed investigation of the Trojan asteroids occupying Jupiter's L4 and L5 Lagrange points as a priority for future NASA mi…
Detection of Thermal Emission from a Super-Earth
Brice-Olivier Demory, Michael Gillon, Sara Seager +3
We report on the detection of infrared light from the super-Earth 55 Cnc e, based on four occultations obtained with Warm Spitzer at 4.5 microns. Our data analysis consists of a tw…
Atmospheric Retrieval for Super-Earths: Uniquely Constraining the Atmospheric Composition with Transmission Spectroscopy
Bjoern Benneke, Sara Seager
We present a retrieval method based on Bayesian analysis to infer the atmospheric compositions and surface or cloud-top pressures from transmission spectra of exoplanets with gener…
