A metal-poor atmosphere with a hot interior for a young sub-Neptune progenitor: JWST/NIRSpec transmission spectrum of V1298 Tau b
Saugata Barat, Jean-Michel Désert, Sagnick Mukherjee +19
We present the JWST/NIRSpec G395H transmission spectrum of the young (10 - 20 Myr old) transiting planet V1298 Tau b (9.85+/-0.35 Re, Teq=670K). Combined HST and JWST observations…
Eclipse Mapping with MIRI: 2D Map of HD 189733b from JWST MIRI LRS Observations
Maura Lally, Ryan Challener, Nikole Lewis +13
Observations and models of transiting hot Jupiter exoplanets indicate that atmospheric circulation features may cause large spatial flux contrasts across their daysides. Previous s…
Possible Carbon Dioxide Above the Thick Aerosols of GJ 1214 b
Everett Schlawin, Kazumasa Ohno, Taylor J. Bell +14
Sub-Neptune planets with radii smaller than Neptune (3.9 Re) are the most common type of planet known to exist in The Milky Way, even though they are absent in the Solar System. Th…
Quartz Clouds in the Dayside Atmosphere of the Quintessential Hot Jupiter HD 189733 b
Julie Inglis, Natasha E. Batalha, Nikole K. Lewis +16
Recent mid-infrared observations with JWST/MIRI have resulted in the first direct detections of absorption features from silicate clouds in the transmission spectra of two transiti…
Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet
Guangwei Fu, Luis Welbanks, Drake Deming +15
As the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization. It has also been the anchor point for much of our theoret…
Sulfur Dioxide and Other Molecular Species in the Atmosphere of the Sub-Neptune GJ 3470 b
Thomas G. Beatty, Luis Welbanks, Everett Schlawin +13
We report observations of the atmospheric transmission spectrum of the sub-Neptune exoplanet GJ 3470 b taken using the Near-Infrared Camera (NIRCam) on JWST. Combined with two arch…
HST PanCET program: A Cloudy Atmosphere for the promising JWST target WASP-101b
H. R. Wakeford, K. B. Stevenson, N. K. Lewis +19
We present results from the first observations of the Hubble Space Telescope (HST) Panchromatic Comparative Exoplanet Treasury (PanCET) program for WASP-101b, a highly inflated hot…
Probing the haze in the atmosphere of HD 189733b with HST/WFC3 transmission spectroscopy
N. P. Gibson, S. Aigrain, F. Pont +6
We present Hubble Space Telescope near-infrared transmission spectroscopy of the transiting exoplanet HD 189733b, using Wide Field Camera 3. This consists of time-series spectra of…
Improving Transit Predictions of Known Exoplanets with TERMS
Stephen R. Kane, David Ciardi, Debra Fischer +7
Transiting planet discoveries have largely been restricted to the short-period or low-periastron distance regimes due to the bias inherent in the geometric transit probability. Thr…
