Interplanetary Dust Ablation Seeds Silicate Clouds in Exoplanet Atmospheres
Sven Kiefer, Gregory J. Gosselin, Caroline V. Morley +1
Interplanetary dust particles (IDPs) are present throughout the Solar System, with Earth experiencing a mass flux of roughly 100 tonnes of IDPs per day. These particles ablate in t…
Phase-dependent chemistry of WASP-43 b revealed with a suite of one-, two-, and three-dimensional models
Robin Baeyens, Julianne I. Moses, Jasmina Blecic +17
Our goal is to investigate the chemistry of the hot Jupiter WASP-43 b in detail using theoretical models, considering the constraints of the James Webb Space Telescope MIRI phase c…
Building a Roadmap for Hubble Science into the 2030s: Revealing Atmospheric Structure and Evolution in Substellar Worlds Using HST
Allison M. McCarthy, Merle A. Schrader, Johanna M. Vos +15
Substellar objects occupy a unique place in our universe, bridging the gap between the smallest stars and the largest planets, and serving as powerful laboratories for understandin…
Connecting JWST Silicate Cloud Observations to Exoplanet Cloud Microphysics with Nimbus
Sven Kiefer, Caroline V. Morley, Melanie Rowland
The unprecedented accuracy of JWST has led to the detection of silicate clouds in exoplanet atmospheres, allowing for the first time to probe cloud formation in extreme environment…
Limb Asymmetries on WASP-39b: A Multi-GCM Comparison of Chemistry, Clouds, and Hazes
Maria E. Steinrueck, Arjun B. Savel, Duncan A. Christie +28
With JWST, observing separate spectra of the morning and evening limbs of hot Jupiters has finally become a reality. The first such observation was reported for WASP-39b, where the…
Why heterogeneous cloud particles matter: Iron-bearing species and cloud particle morphology affects exoplanet transmission spectra
Sven Kiefer, Dominic Samra, David A. Lewis +5
The possibility of observing spectral features in exoplanet atmospheres with space missions like JWST and ARIEL necessitates the accurate modelling of cloud particle opacities. In…
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…
The effect of thermal non-equilibrium on kinetic nucleation
Sven Kiefer, David Gobrecht, Leen Decin +1
Nucleation is considered to be the first step in dust and cloud formation in the atmospheres of asymptotic giant branch (AGB) stars, exoplanets, and brown dwarfs. In these environm…
Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
Jamie Tayar, Facundo D. Moyano, Melinda Soares-Furtado +15
In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the…
Exploring the deep atmospheres of HD 209458b and WASP-43b using a non-gray general circulation model
Aaron David Schneider, Ludmila Carone, Leen Decin +5
Simulations with a 3D general circulation model (GCM) suggest that one potential driver behind the observed radius inflation in hot Jupiters may be the downward advection of energy…
