Magnetic field strengths of hot giant exoplanets consistent with Solar System values
Julia V. Seidel, Vivien Parmentier, Bibiana Prinoth +29
Magnetic fields are ubiquitous in the universe. They play a key role in shaping the activity of stars, the habitability of rocky planets, and the long-term retention of planetary a…
Unraveling the Mystery of the Peculiar and Young Hot Jupiter CoRoT-2b. I. HO and CO Detection from Dayside Observations with Gemini-S/IGRINS
Ying Shu, Lisa Dang, Antoine Darveau-Bernier +12
We present ground-based high-resolution spectroscopic pre-eclipse observations of the hot Jupiter CoRoT-2b obtained with the IGRINS spectrograph on Gemini South. Using cross-correl…
A Panchromatic Characterization of the Evening and Morning Atmosphere of WASP-107 b: Composition and Cloud Variations, and Insight into the Effect of Stellar Contamination
Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +16
Limb-resolved transmission spectroscopy has the potential to transform our understanding of exoplanetary atmospheres. By separately measuring the transmission spectra of the evenin…
The radiative effects of photochemical hazes on the atmospheric circulation and phase curves of sub-Neptunes
Maria E. Steinrueck, Vivien Parmentier, Laura Kreidberg +13
Measuring the atmospheric composition of hazy sub-Neptunes like GJ~1214b through transmission spectroscopy is difficult because of the degeneracy between mean molecular weight and…
Clouds and Hazes in GJ 1214b's Metal-Rich Atmosphere
Isaac Malsky, Emily Rauscher, Kevin Stevenson +10
The sub-Neptune GJ 1214b has an infamously flat transmission spectrum, likely due to thick aerosols in its atmosphere. A recent JWST MIRI spectroscopic phase curve of GJ 1214 b add…
An Analysis of Spitzer Phase Curves for WASP-121b and WASP-77Ab
Brian Davenport, Thomas Kennedy, E. M. May +6
We present analyses of Spitzer InfraRed Array Camera (IRAC) 3.6 m and 4.5 m phase curve observations of hot Jupiters WASP-77Ab and WASP-121b. For WASP-121b, we find amplitude…
A Measurement of the Water Abundance in the Atmosphere of the Hot Jupiter WASP-43b with High-resolution Cross-correlation Spectroscopy
Dare Bartelt, Megan Weiner Mansfield, Michael R. Line +8
Measuring the abundances of carbon- and oxygen-bearing molecules has been a primary focus in studying the atmospheres of hot Jupiters, as doing so can help constrain the carbon-to-…
The Roasting Marshmallows Program with IGRINS on Gemini South II -- WASP-121 b has super-stellar C/O and refractory-to-volatile ratios
Peter C. B. Smith, Jorge A. Sanchez, Michael R. Line +19
A primary goal of exoplanet science is to measure the atmospheric composition of gas giants in order to infer their formation and migration histories. Common diagnostics for planet…
A Comprehensive Analysis Spitzer 4.5 m Phase Curve of Hot Jupiters
Lisa Dang, Taylor J. Bell, Ying +19
Although exoplanetary science was not initially projected to be a substantial part of the Spitzer mission, its exoplanet observations set the stage for current and future surveys w…
Inhomogeneous terminators on the exoplanet WASP-39 b
Néstor Espinoza, Maria E. Steinrueck, James Kirk +40
Transmission spectroscopy has been a workhorse technique over the past two decades to constrain the physical and chemical properties of exoplanet atmospheres. One of its classical…
Multiple Clues for Dayside Aerosols and Temperature Gradients in WASP-69 b from a Panchromatic JWST Emission Spectrum
Everett Schlawin, Sagnick Mukherjee, Kazumasa Ohno +16
WASP-69 b is a hot, inflated, Saturn-mass planet 0.26 Mjup with a zero-albedo equilibrium temperature of 963 K. Here, we report the JWST 2 to 12 um emission spectrum of the planet…
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…
The metallicity and carbon-to-oxygen ratio of the ultra-hot Jupiter WASP-76b from Gemini-S/IGRINS
Megan Weiner Mansfield, Michael R. Line, Joost P. Wardenier +11
Measurements of the carbon-to-oxygen (C/O) ratios of exoplanet atmospheres can reveal details about their formation and evolution. Recently, high-resolution cross-correlation analy…
Evidence for Morning-to-Evening Limb Asymmetry on the Cool Low-Density Exoplanet WASP-107b
Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +8
The atmospheric properties of hot exoplanets are expected to be different between the morning and the evening limb due to global atmospheric circulation. Ground-based observations…
A High Internal Heat Flux and Large Core in a Warm Neptune Exoplanet
Luis Welbanks, Taylor J. Bell, Thomas G. Beatty +16
Interactions between exoplanetary atmospheres and internal properties have long been hypothesized to be drivers of the inflation mechanisms of gaseous planets and apparent atmosphe…
