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…

Outbursts and Disk Variability in Be Stars

Jonathan Labadie-Bartz, S. Drew Chojnowski, David G. Whelan +16

In order to study the growth and evolution of circumstellar disks around classical Be stars, we analyze optical time-series photometry from the KELT survey with simultaneous infrar…

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,…

KELT-18b: Puffy Planet, Hot Host, Probably Perturbed

Kim K. McLeod, Joseph E. Rodriguez, Ryan J. Oelkers +53

We report the discovery of KELT-18b, a transiting hot Jupiter in a 2.87d orbit around the bright (V=10.1), hot, F4V star BD+60 1538 (TYC 3865-1173-1). We present follow-up photomet…
