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…
Determining Empirical Stellar Masses and Radii Using Transits and Gaia Parallaxes as Illustrated by Spitzer Observations of KELT-11b
Thomas G. Beatty, Daniel J. Stevens, Karen A. Collins +8
Using the Spitzer Space Telescope, we observed a transit at 3.6um of KELT-11b (Pepper et al. 2017). We also observed three partial transits from the ground. We simultaneously fit t…
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…
The Broadband and Spectrally-Resolved H-band Eclipse of KELT-1b and the Role of Surface Gravity in Stratospheric Inversions in Hot Jupiters
Thomas G. Beatty, Nikku Madhusudhan, Richard Pogge +4
We present a high precision H-band emission spectrum of the transiting brown dwarf KELT-1b, which we spectrophotometrically observed during a single secondary eclipse using the LUC…
Reverberation Mapping of Optical Emission Lines in Five Active Galaxies
M. M. Fausnaugh, C. J. Grier, M. C. Bentz +68
We present the first results from an optical reverberation mapping campaign executed in 2014, targeting the active galactic nuclei (AGN) MCG+08-11-011, NGC 2617, NGC 4051, 3C 382,…
KELT-12b: A Day, Highly Inflated Hot Jupiter Transiting a Mildly Evolved Hot Star
Daniel J. Stevens, Karen A. Collins, B. Scott Gaudi +46
We report the discovery of KELT-12b, a highly inflated Jupiter-mass planet transiting a mildly evolved host star. We identified the initial transit signal in the KELT-North survey…
