A Global Perspective with Updated Constraints on the Ultra-hot Jupiter WASP-19b: Atmospheric Properties and Stellar Activity
Abigail A. Tumborang, Jessica J. Spake, Heather A. Knutson +7
We present a detailed reanalysis of the atmospheric properties of WASP-19b, an ultra-hot Jupiter (1.14 M Jup, 1.41 R Jup) orbiting an active Sun-like star every 0.79 day. We reanal…
JWST/NIRISS reveals the water-rich "steam world" atmosphere of GJ 9827 d
Caroline Piaulet-Ghorayeb, Bjorn Benneke, Michael Radica +30
With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While t…
The Clear Sky Corridor: Insights Towards Aerosol Formation in Exoplanets Using An AI-based Survey of Exoplanet Atmospheres
Reza Ashtari, Kevin B. Stevenson, David Sing +4
Producing optimized and accurate transmission spectra of exoplanets from telescope data has traditionally been a manual and labor-intensive procedure. Here we present the results o…
The Featherweight Giant: Unraveling the Atmosphere of a 17 Myr Planet with JWST
Pa Chia Thao, Andrew W. Mann, Adina D. Feinstein +29
The characterization of young planets (< 300 Myr) is pivotal for understanding planet formation and evolution. We present the 3-5m transmission spectrum of the 17 Myr, Jupiter-s…
Longitudinal Filtering, Sponge Layers, and Equatorial Jet Formation in a General Circulation Model of Gaseous Exoplanets
D. A. Christie, N. J. Mayne, M. Zamyatina +4
General circulation models are a useful tool in understanding the three dimensional structure of hot Jupiter and sub-Neptune atmospheres; however, understanding the validity of the…
HST SHEL: Enabling Comparative Exoplanetology with HST/STIS
Natalie H. Allen, David K. Sing, Néstor Espinoza +12
The Hubble Space Telescope (HST) has been our most prolific tool to study exoplanet atmospheres. As the age of JWST begins, there is a wealth of HST archival data that is useful to…
JWST Reveals CH, CO, and HO in a Metal-rich Miscible Atmosphere on a Two-Earth-Radius Exoplanet
Björn Benneke, Pierre-Alexis Roy, Louis-Philippe Coulombe +28
Even though sub-Neptunes likely represent the most common outcome of planet formation, their natures remain poorly understood. In particular, planets near 1.5-2.5 often…
How do wavelength correlations affect transmission spectra? Application of a new fast and flexible 2D Gaussian process framework to transiting exoplanet spectroscopy
Mark Fortune, Neale P. Gibson, Daniel Foreman-Mackey +3
The use of Gaussian processes (GPs) is a common approach to account for correlated noise in exoplanet time series, particularly for transmission and emission spectroscopy. This ana…
