A survey of eight hot Jupiters in secondary eclipse using WIRCam at CFHT
Eder Martioli, Knicole D. Colón, Daniel Angerhausen +12
We present near infrared high-precision photometry for eight transiting hot Jupiters observed during their predicted secondary eclipses. Our observations were carried out using the…
The DEdicated MONitor of EXotransits and Transients (DEMONEXT): System Overview and Year One Results from a Low-Cost Robotic Telescope for Follow-Up of Exoplanetary Transits and Transients
Steven Villanueva, B. Scott Gaudi, Richard W. Pogge +4
We report on the design and first year of operations of the DEdicated MONitor of EXotransits and Transients (DEMONEXT). DEMONEXT is a 20 inch (0.5-m) robotic telescope using a Plan…
KELT-19Ab: A P~4.6 Day Hot Jupiter Transiting a Likely Am Star with a Distant Stellar Companion
Robert J. Siverd, Karen A. Collins, George Zhou +51
We present the discovery of the giant planet KELT-19Ab, which transits the moderately bright A8V star TYC 764-1494-1 with an orbital period of 4.61 days. We…
A System of Three Super Earths Transiting the Late K-Dwarf GJ 9827 at Thirty Parsecs
Joseph E. Rodriguez, Andrew Vanderburg, Jason D. Eastman +5
We report the discovery of three small transiting planets orbiting GJ 9827, a bright (K = 7.2) nearby late K-type dwarf star. GJ 9827 hosts a super E…
KELT-20b: A giant planet with a period of P~ 3.5 days transiting the V~ 7.6 early A star HD 185603
Michael B. Lund, Joseph E. Rodriguez, George Zhou +46
We report the discovery of KELT-20b, a hot Jupiter transiting a V~7.6 early A star with an orbital period of P~3.47 days. We identified the initial transit signal in KELT-North sur…
A giant planet undergoing extreme ultraviolet irradiation by its hot massive-star host
B. Scott Gaudi, Keivan G. Stassun, Karen A. Collins +57
The amount of ultraviolet irradiation and ablation experienced by a planet depends strongly on the temperature of its host star. Of the thousands of extra-solar planets now known,…
