Spitzer Secondary Eclipse Depths with Multiple Intrapixel Sensitivity Correction Methods: Observations of WASP-13b, WASP-15b, WASP-16b, WASP-62b, and HAT-P-22b
Brian M. Kilpatrick, Nikole K. Lewis, Tiffany Kataria +4
We measure the 4.5 m thermal emission of five transiting hot Jupiters, WASP-13b, WASP-15b, WASP-16b, WASP-62b and HAT-P-22b using channel 2 of the Infrared Array Camera (IRAC) o…
High temperature condensate clouds in super-hot Jupiter atmospheres
Hannah R. Wakeford, Channon Visscher, Nikole K. Lewis +4
Deciphering the role of clouds is central to our understanding of exoplanet atmospheres, as they have a direct impact on the temperature and pressure structure, and observational p…
VLT FORS2 comparative transmission spectroscopy: Detection of Na in the atmosphere of WASP-39b from the ground
Nikolay Nikolov, David K. Sing, Neale P. Gibson +5
We present transmission spectroscopy of the warm Saturn-mass exoplanet WASP-39b made with the Very Large Telescope (VLT) FOcal Reducer and Spectrograph (FORS2) across the wavelengt…
Spitzer Phase Curve Constraints for WASP-43b at 3.6 and 4.5 microns
Kevin B. Stevenson, Michael R. Line, Jacob L. Bean +6
Previous measurements of heat redistribution efficiency (the ability to transport energy from a planet's highly irradiated dayside to its eternally dark nightside) show considerabl…
A map of the large day-night temperature gradient of a super-Earth exoplanet
Brice-Olivier Demory, Michael Gillon, Julien de Wit +11
Over the past decade, observations of giant exoplanets (Jupiter-size) have provided key insights into their atmospheres, but the properties of lower-mass exoplanets (sub-Neptune) r…
Detection of H2O and evidence for TiO/VO in an ultra hot exoplanet atmosphere
Thomas M. Evans, David K. Sing, Hannah R. Wakeford +7
We present a primary transit observation for the ultra hot (Teq~2400K) gas giant expolanet WASP-121b, made using the Hubble Space Telescope Wide Field Camera 3 in spectroscopic mod…
The atmospheric circulation of a nine-hot Jupiter sample: Probing circulation and chemistry over a wide phase space
Tiffany Kataria, David K. Sing, Nikole K. Lewis +4
We present results from an atmospheric circulation study of nine hot Jupiters that comprise a large transmission spectral survey using the Hubble and Spitzer Space Telescopes. Thes…
Transiting Exoplanet Studies and Community Targets for JWST's Early Release Science Program
Kevin B. Stevenson, Nikole K. Lewis, Jacob L. Bean +49
The James Webb Space Telescope will revolutionize transiting exoplanet atmospheric science due to its capability for continuous, long-duration observations and its larger collectin…
HST hot-Jupiter transmission spectral survey: Clear skies for cool Saturn WASP-39b
Patrick D. Fischer, Heather A. Knutson, David K. Sing +13
We present HST STIS optical transmission spectroscopy of the cool Saturn-mass exoplanet WASP-39b from 0.29-1.025 micron, along with complementary transit observations from Spitzer…
