K2-114b and K2-115b: Two Transiting Warm Jupiters
Avi Shporer, George Zhou, Benjamin J. Fulton +22
We report the first results from a search for transiting warm Jupiter exoplanets - gas giant planets receiving stellar irradiation below about erg s cm, equiva…
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…
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…
AstroImageJ: Image Processing and Photometric Extraction for Ultra-Precise Astronomical Light Curves (Expanded Edition)
Karen A. Collins, John F. Kielkopf, Keivan G. Stassun +1
ImageJ is a graphical user interface (GUI) driven, public domain, Java-based, software package for general image processing traditionally used mainly in life sciences fields. The i…
