HST-COS Transit Spectroscopy of KELT-20b: First Detection of Excess Far-ultraviolet Absorption From an Ultra-hot Jupiter
Patrick R. Behr, Kevin France, Luca Fossati +4
KELT-20 b is an ultra-hot Jupiter with an equilibrium temperature of K orbiting a bright (V =7.6), fast-rotating (=117 km s) A2 V star. The atmosphere of KE…
Colorado Ultraviolet Transit Experiment Near-Ultraviolet Transmission Spectroscopy of the Ultra-hot Jupiter KELT-9b
Arika Egan, Kevin France, Aickara Gopinathan Sreejith +9
We present new near-ultraviolet (NUV, = 2479 3306 ) transmission spectroscopy of KELT-9b, the hottest known exoplanet, obtained with the Colorado Ultraviolet Transit Exp…
The High-Energy Spectrum of the Young Planet Host V1298 Tau
Girish M. Duvvuri, P. Wilson Cauley, Fernando Cruz Aguirre +4
V1298 Tau is a young pre-main sequence star hosting four known exoplanets that are prime targets for transmission spectroscopy with current-generation instruments. This work pieces…
CUTE reveals escaping metals in the upper atmosphere of the ultra-hot Jupiter WASP-189b
A. G. Sreejith, Kevin France, Luca Fossati +12
Ultraviolet observations of Ultra-hot Jupiters (UHJs), exoplanets with temperatures over 2000\,K, provide us with an opportunity to investigate if and how atmospheric escape shapes…
The Radial Distribution and Excitation of H2 around Young Stars in the HST-ULLYSES Survey
Kevin France, Nicole Arulanantham, Erin Maloney +8
The spatial distribution and evolution of gas in the inner 10 au of protoplanetary disks form the basis for estimating the initial conditions of planet formation. Among the most im…
Flares, Rotation, Activity Cycles and a Magnetic Star-Planet Interaction Hypothesis for the Far Ultraviolet Emission of GJ 436
R. O. Parke Loyd, P. C. Schneider, James A. G. Jackman +6
Variability in the far ultraviolet (FUV) emission produced by stellar activity affects photochemistry and heating in orbiting planetary atmospheres. We present a comprehensive anal…
