Transmission Spectroscopy of WASP-79b from 0.6 to 5.0 m
Kristin S. Sotzen, Kevin B. Stevenson, David K. Sing +18
As part of the PanCET program, we have conducted a spectroscopic study of WASP-79b, an inflated hot Jupiter orbiting an F-type star in Eridanus with a period of 3.66 days. Building…
Detection of Na, K and HO in the hazy atmosphere of WASP-6b
Aarynn L. Carter, Nikolay Nikolov, David K. Sing +13
We present new observations of the transmission spectrum of the hot Jupiter WASP-6b both from the ground with the Very Large Telescope (VLT) FOcal Reducer and Spectrograph (FORS2)…
WASP-127b transmission spectrum]{Abundance measurements of HO and carbon-bearing species in the atmosphere of WASP-127b confirm its super-solar metallicity
Jessica J. Spake, David K. Sing, Hannah R. Wakeford +14
The chemical abundances of exoplanet atmospheres may provide valuable information about the bulk compositions, formation pathways, and evolutionary histories of planets. Exoplanets…
WASP-52b. The effect of starspot correction on atmospheric retrievals
Giovanni Bruno, Nikole K. Lewis, Munazza K. Alam +13
We perform atmospheric retrievals on the full optical to infrared () transmission spectrum of the inflated hot Jupiter WASP-52b by combining HST/STIS, WFC3 IR…
A Hubble PanCET Study of HAT-P-11b: A Cloudy Neptune with a Low Atmospheric Metallicity
Yayaati Chachan, Heather A. Knutson, Peter Gao +14
We present the first comprehensive look at the m transmission spectrum of the warm ( K) Neptune HAT-P-11b derived from thirteen individual transits observed u…
The Hubble PanCET program: An extensive search for metallic ions in the exosphere of GJ 436 b
L. A. dos Santos, D. Ehrenreich, V. Bourrier +15
(Abridged) The quiet M2.5 star GJ 436 hosts a warm Neptune that displays an extended atmosphere that dwarfs its own host star. Predictions of atmospheric escape in such planets sta…
The HST PanCET Program: Exospheric Mg II and Fe II in the Near-UV transmission spectrum of WASP-121b using Jitter Decorrelation
David K. Sing, Panayotis Lavvas, Gilda E. Ballester +17
We present HST near-ultraviolet (NUV) transits of the hot Jupiter WASP-121b, acquired as part of the PanCET program. Time series spectra during two transit events were used to meas…
An emission spectrum for WASP-121b measured across the 0.8-1.1 micron wavelength range using the Hubble Space Telescope
Thomas Mikal-Evans, David K. Sing, Jayesh M. Goyal +11
WASP-121b is a transiting gas giant exoplanet orbiting close to its Roche limit, with an inflated radius nearly double that of Jupiter and a dayside temperature comparable to a lat…
Understanding Exoplanet Atmospheres with UV Observations I: NUV and Blue/Optical
Jessie L. Christiansen, Thomas Barclay, Luca Fossati +6
Much of the focus of exoplanet atmosphere analysis in the coming decade will be atinfrared wavelengths, with the planned launches of the James Webb Space Telescope (JWST) and the W…
Statistical Characterization of Hot Jupiter Atmospheres using Spitzer's Secondary Eclipses
Emily Garhart, Drake Deming, Avi Mandell +15
We report 78 secondary eclipse depths for a sample of 36 transiting hot Jupiters observed at 3.6- and 4.5 microns using the Spitzer Space Telescope. Our eclipse results for 27 of t…
