Absolute dimensions of the eccentric eclipsing binary V541 Cygni
G. Torres, C. D. McGruder, R. J. Siverd +6
We report new spectroscopic and photometric observations of the main-sequence, detached, eccentric, double-lined eclipsing binary V541 Cyg (P = 15.34 days, e = 0.468). Using these…
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…
Photometric Variability of the Be Star Population
Jonathan Labadie-Bartz, Joshua Pepper, M. Virginia McSwain +11
Be stars have generally been characterized by the emission lines in their spectra, and especially the time variability of those spectroscopic features. They are known to also exhib…
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…
DM Ori: A Young Star Occulted by a Disturbance in its Protoplanetary Disk
Joseph E. Rodriguez, Keivan G. Stassun, Phillip Cargile +15
In some planet formation theories, protoplanets grow gravitationally within a young star's protoplanetary disk, a signature of which may be a localized disturbance in the disk's ra…
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…
An Extreme Analogue of Aurigae: An M-giant Eclipsed Every 69 Years by a Large Opaque Disk Surrounding a Small Hot Source
Joseph E. Rodriguez, Keivan G. Stassun, Michael B. Lund +10
We present TYC 2505-672-1 as a newly discovered and remarkable eclipsing system comprising an M-type red giant that undergoes a ~3.45 year long, near-total eclipse (depth of ~4.5 m…
