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…
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…
KELT-16b: A highly irradiated, ultra-short period hot Jupiter nearing tidal disruption
Thomas E. Oberst, Joseph E. Rodriguez, Knicole D. Colón +47
We announce the discovery of KELT-16b, a highly irradiated, ultra-short period hot Jupiter transiting the relatively bright () star TYC 2688-1839-1. A global analysis of…
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…
KELT-17b: A hot-Jupiter transiting an A-star in a misaligned orbit detected with Doppler tomography
George Zhou, Joseph E. Rodriguez, Karen A. Collins +45
We present the discovery of a hot-Jupiter transiting the V=9.23 mag main-sequence A-star KELT-17 (BD+14 1881). KELT-17b is a 1.31 -0.29/+0.28 Mj, 1.525 -0.060/+0.065 Rj hot-Jupiter…
A statistical analysis of the accuracy of the digitized magnitudes of photometric plates on the time scale of decades with an application to the century-long light curve of KIC 8462852
Michael Hippke, Daniel Angerhausen, Michael B. Lund +2
We present a statistical analysis of the accuracy of the digitized magnitudes of photometric plates on the time scale of decades. In our examination of archival Johnson B photometr…
