The coupled impacts of atmospheric dynamics and cloud microphysics on hot Jupiter atmospheres. I. An application to WASP-43b
Emeline F. Fromont, Thaddeus D. Komacek, Peter Gao +9
Understanding the influence of cloud-circulation feedback on planetary climates is crucial to interpreting solar system and extrasolar planet observations. Hot Jupiter phase curve…
Inhomogeneous Cloud Coverage and Altitude-Dependent Heat Transport on the Hot-Jupiter NGTS-10 Ab from its Optical-to-Infrared Phase Curve
Louis-Philippe Coulombe, Vivien Parmentier, Kevin B. Stevenson +15
Hot-Jupiters, gas giant planets with equilibrium temperatures above 1,000 K, host large temperature gradients between their permanent day- and nightsides, resulting in circulation…
JWST MIRI reveals a potential atmosphere on the ultra-hot rocky planet TOI-431b
Cole Smith, Brandon Park Coy, Megan Weiner Mansfield +13
An open question in exoplanet science is whether rocky exoplanets extremely close in to their host stars, `lava worlds', can retain significant atmospheres. Thermal emission observ…
Magnesium silicate condensation in sub-Neptune envelopes: the fundamental link between chemistry, structure, and observables
William Misener, Peter Gao, Nicole L. Wallack +2
Chemical interactions between the hydrogen-dominated envelopes and silicate-rich interiors of sub-Neptunes likely play a key role in shaping their atmospheric structure, mass-radiu…
Wet Removal and Cloud Enhancement: The Microphysics of Cloud-Haze Interactions on Sub-Neptunes
Vighnesh Nagpal, Maria Steinrueck, Diana Powell +3
Aerosols are a near-ubiquitous feature of sub-Neptune atmospheres, yet their microphysical nature remains poorly understood. Both condensate clouds and photochemical hazes have bee…
GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere
Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16
HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…
CARMApy: An Open-Source Python Framework for Simulating Microphysical Clouds in Planetary Atmospheres
Wolf Cukier, Diana Powell, Xi Zhang +3
CARMApy is a new open-source python code that performs bin-scheme microphysical modeling of clouds in exoplanet atmospheres. It models key cloud properties such as particle size di…
C, N, O, S, and photochemistry in a temperate giant planet orbiting a late M dwarf
Michael Zhang, Qiao Xue, Jeehyun Yang +20
We report the JWST NIRSpec/PRISM transit spectrum of TOI-6894b, an exceptional 420 K sub-Saturn that is one of the rare giant planets transiting a late M dwarf. Remarkably, both th…
Hydrogen and Helium Dissolution, Outgassing, and Loss in Evolving Sub-Neptune Magma Oceans: Examining Demographic Features and Radius Evolution
Yao Tang, Jonathan J. Fortney, Laura K. Schaefer +1
Sub-Neptunes' molten interiors are expected to accommodate large quantities of volatiles, potentially altering their radius evolution. Previous studies have examined this effect in…
Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres
Jeehyun Yang, Vighnesh Nagpal, Michael Zhang +16
Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in…
Horizontal transport as a source of disequilibrium chemistry on the nightside of a hot exoplanet
Vivien Parmentier, Kevin B. Stevenson, Luis Welbanks +15
Hot Jupiters have temperature gradients of several hundreds of degrees between their permanent day and nightsides. In equilibrium, the primary carbon reservoir is expected to trans…
Evidence for an Atmosphere on the Ultra-Short Period super-Earth HD 3167 b
Brandon Park Coy, Qiao Xue, Megan Weiner Mansfield +14
'Lava worlds'-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characteriza…
