Evidence for Atmospheric Cold-trap Processes in the Noninverted Emission Spectrum of Kepler-13Ab Using HST/WFC3
Thomas G. Beatty, Nikku Madhusudhan, Angelos Tsiaras +5
We observed two eclipses of the Kepler-13A planetary system, on UT 2014 April 28 and UT 2014 October 13, in the near-infrared using Wide Field Camera 3 on the Hubble Space Telescop…
Near-Infrared Emission Spectrum of WASP-103b using Hubble Space Telescope/Wide Field Camera 3
Kimberly M. S. Cartier, Thomas G. Beatty, Ming Zhao +8
We present here our observations and analysis of the dayside emission spectrum of the hot Jupiter WASP-103b. We observed WASP-103b during secondary eclipse using two visits of the…
Families of Plausible Solutions to the Puzzle of Boyajian's Star
Jason T. Wright, Steinn Sigurdsson
Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaef…
A comprehensive radial velocity error budget for next generation Doppler spectrometers
Samuel Halverson, Ryan Terrien, Suvrath Mahadevan +14
We describe a detailed radial velocity error budget for the NASA-NSF Extreme Precision Doppler Spectrometer instrument concept NEID (NN-explore Exoplanet Investigations with Dopple…
KELT-11b: A Highly Inflated Sub-Saturn Exoplanet Transiting the V=8 Subgiant HD 93396
Joshua Pepper, Joseph E. Rodriguez, Karen A. Collins +34
We report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright () subgiant HD 93396. A global analysis of the system shows that the host star is an evolved…
Three Temperate Neptunes Orbiting Nearby Stars
Benjamin J. Fulton, Andrew W. Howard, Lauren M. Weiss +17
We present the discovery of three modestly-irradiated, roughly Neptune-mass planets orbiting three nearby Solar-type stars. HD 42618 b has a minimum mass of M$_{\opl…
