A Comparison of 1D and 3D Exoplanet Atmosphere Model Grids: ScCHIMERA and the SPARC/MITgcm
Lindsey S. Wiser, Alexander Roth, Vivien Parmentier +1
Inferring the properties of transiting exoplanet atmospheres relies on comparing models to spectroscopic observations. Atmosphere models, however, make a range of assumptions, from…
The SPHINX M dwarf Spectral Grid. II. New Model Atmospheres and Spectra to Derive Fundamental Properties of mid-to-late type M-dwarfs
Aishwarya R. Iyer, Michael R. Line, Philip S. Muirhead +2
M-dwarfs are the most dominant stars in the Galaxy. Their interiors and atmospheres exhibit complex processes including dust condensation, convective feedback, and magnetic activit…
The Sonora Substellar Atmosphere Models VI. Red Diamondback: Extending Diamondback with SPHINX for Brown Dwarf Early Evolution
C. Evan Davis, Jonathan J. Fortney, Aishwarya Iyer +5
We extend the Sonora Diamondback brown dwarf evolution models to higher effective temperatures to treat the evolution of younger, higher mass objects. Due to an upper temperature l…
Cloudy solutions for the clear skies of WASP-80b: 3D cloud feedback on the atmosphere and spectra of a warm Jupiter
Nishil Mehta, Vivien Parmentier, Xianyu Tan +14
Close-in warm Jupiters orbiting M dwarf stars are expected to exhibit diverse atmospheric chemistry, with clouds playing a key role in shaping their albedo, heat distribution, and…
A Precise Metallicity and Carbon-to-Oxygen Ratio for a Warm Giant Exoplanet from its Panchromatic JWST Emission Spectrum
Lindsey S. Wiser, Taylor J. Bell, Michael R. Line +11
WASP-80 b, a warm sub-Jovian (equilibrium temperature ~820 K, 0.5 Jupiter masses), presents an opportunity to characterize a rare gas giant exoplanet around a low-mass star. In add…
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…
Challenges in the detection of gases in exoplanet atmospheres
Luis Welbanks, Matthew C. Nixon, Peter McGill +12
Claims of detections of gases in exoplanet atmospheres often rely on comparisons between models including and excluding specific chemical species. However, the space of molecular c…
Enabling Robust Exoplanet Atmospheric Retrievals with Gaussian Processes
Yoav Rotman, Luis Welbanks, Michael R. Line +3
Atmospheric retrievals are essential tools for interpreting exoplanet transmission and eclipse spectra, enabling quantitative constraints on the chemical composition, aerosol prope…
A JWST Panchromatic Thermal Emission Spectrum of the Warm Neptune Archetype GJ 436b
Sagnick Mukherjee, Everett Schlawin, Taylor J. Bell +10
GJ 436b is the archetype warm Neptune exoplanet. The planet's thermal emission spectrum was previously observed via intensive secondary eclipse campaigns with Spitzer. The atmosphe…
