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…
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…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. IX: The Ninth Year (2016-2017)
Taichi Kato, Keisuke Isogai, Franz-Josef Hambsch +76
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 127 SU UMa-type dwarf novae observed mainly during the 2016--201…
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,…
A Bright Short Period M-M Eclipsing Binary from the KELT Survey: Magnetic Activity and the Mass-Radius Relationship for M-dwarfs
Jack B. Lubin, Joseph E. Rodriguez, George Zhou +26
We report the discovery of KELT J041621-620046, a moderately bright (J10.2) M dwarf eclipsing binary system at a distance of 393 pc. KELT J041621-620046 was first identi…
An Investigation of Four Chemically Peculiar Stars with Photometric Periods below 12 Hours
Stefan Hümmerich, Klaus Bernhard, Ernst Paunzen +3
We present an investigation of three chemically peculiar (CP) stars and one CP star candidate which exhibit photometric periods below 12 hours. New spectroscopic observations have…
