Large Interferometer For Exoplanets (LIFE): IX. Assessing the Impact of Clouds on Atmospheric Retrievals at Mid-Infrared Wavelengths with a Venus-Twin Exoplanet
B. S. Konrad, E. Alei, S. P. Quanz +10
The Large Interferometer For Exoplanets (LIFE) initiative aims to develop a space based mid-infrared (MIR) nulling interferometer to measure the thermal emission spectra of tempera…
Moist convection is most vigorous at intermediate atmospheric humidity
Jacob T. Seeley, Robin D. Wordsworth
In Earth's current climate, moist convective updraft speeds increase with surface warming. This trend suggests that very vigorous convection might be the norm in extremely hot and…
Prospects for water vapor detection in the atmospheres of temperate and arid rocky exoplanets around M-dwarf stars
Feng Ding, Robin D. Wordsworth
Detection of water vapor in the atmosphere of temperate rocky exoplanets would be a major milestone on the path towards characterization of exoplanet habitability. Past modeling wo…
Episodic deluges in simulated hothouse climates
Jacob Seeley, Robin Wordsworth
Earth's distant past and potentially its future include extremely warm "hothouse" climate states, but little is known about how the atmosphere behaves in such states. One distingui…
Multiple moist climate equilibrium states on arid rocky M-dwarf planets: A last-saturation tracer analysis
Feng Ding, Robin D. Wordsworth
Terrestrial-type exoplanets orbiting nearby red dwarf stars (M dwarfs) are the first potentially habitable exoplanets suitable for atmospheric characterization in the near future.…
How likely are Snowball episodes near the inner edge of the habitable zone?
R. Wordsworth
Understanding when global glaciations occur on Earth-like planets is a major challenge in climate evolution research. Most models of how greenhouse gases like CO2 evolve with time…
A coupled model of episodic warming, oxidation and geochemical transitions on early Mars
Robin Wordsworth, Andrew H. Knoll, Joel Hurowitz +4
Reconciling the geology of Mars with models of atmospheric evolution remains a major challenge. Martian geology is characterized by past evidence for episodic surface liquid water,…
The Physics of Falling Raindrops in Diverse Planetary Atmospheres
Kaitlyn Loftus, Robin Wordsworth
The evolution of a single raindrop falling below a cloud is governed by fluid dynamics and thermodynamics fundamentally transferable to planetary atmospheres beyond modern Earth's.…
Comet-like tails of disintegrating exoplanets explained by escaping outflows emanated from the permanent nightside: day-side versus night-side escape
Wanying Kang, Feng Ding, Robin Wordsworth +1
Ultra-hot disintegrating exoplanets have been detected with tails trailing behind and/or shooting ahead of them. These tails are believed to be made of dusts that are carried upwar…
Extremely long convergence times in a 3D GCM simulation of the sub-Neptune Gliese 1214b
Huize Wang, Robin Wordsworth
We present gray gas general circulation model (GCM) simulations of the tidally locked mini-Neptune GJ 1214b. On timescales of 1,000-10,000 Earth days, our results are comparable to…
Earths polar night boundary layer as an analogue for dark side inversions on synchronously rotating terrestrial exoplanets
Manoj Joshi, Andrew Elvidge, Robin Wordsworth +1
A key factor in determining the potential habitability of synchronously rotating planets is the strength of the atmospheric boundary layer inversion between the dark side surface a…
Stabilization of dayside surface liquid water via tropopause cold trapping on arid slowly rotating tidally locked planets
Feng Ding, Robin D. Wordsworth
Terrestrial-type exoplanets orbiting nearby red dwarf stars (M-dwarfs) are among the best targets for atmospheric characterization and biosignature searches in the near future. Rec…
Collapse of the general circulation in shortwave-absorbing atmospheres: an idealized model study
Wanying Kang, Robin Wordsworth
The response of the general circulation in a dry atmosphere to various atmospheric shortwave absorptivities is investigated in a three-dimensional general circulation model with gr…
Jupiter's composition suggests its core assembled exterior to the N2 snowline
Karin I. Oberg, Robin Wordsworth
Jupiter's atmosphere is enriched in C, N, S, P, Ar, Kr and Xe with respect to solar abundances by a factor of ~3. Gas Giant envelopes are mainly enriched through the dissolution of…
Sulfate Aerosol Hazes and SO2 Gas as Constraints on Rocky Exoplanets' Surface Liquid Water
Kaitlyn Loftus, Robin D. Wordsworth, Caroline V. Morley
Despite surface liquid water's importance to habitability, observationally diagnosing its presence or absence on exoplanets is still an open problem. Inspired within the Solar Syst…
Growth Model Interpretation of Planet Size Distribution
Li Zeng, Stein B. Jacobsen, Dimitar D. Sasselov +13
The radii and orbital periods of 4000+ confirmed/candidate exoplanets have been precisely measured by the Kepler mission. The radii show a bimodal distribution, with two peaks corr…
Atmospheric Evolution on Low-gravity Waterworlds
Constantin W. Arnscheidt, Robin D. Wordsworth, Feng Ding
Low-gravity waterworlds () are of interest for their potential habitability. The weakly bound atmospheres of such worlds have proportionally larger radiat…
A New Line-By-Line General Circulation Model for Simulations of Diverse Planetary Atmospheres: Initial Validation and Application to the Exoplanet GJ 1132b
Feng Ding, Robin D. Wordsworth
Exploring diverse planetary atmospheres requires modeling tools that are both accurate and flexible. Here, we develop a three-dimensional general circulation model (3D GCM) that fo…
The Importance of 3D General Circulation Models for Characterizing the Climate and Habitability of Terrestrial Extrasolar Planets
Eric T. Wolf, Ravi Kopparapu, Vladimir Airapetian +27
While recently discovered exotic new planet-types have both challenged our imaginations and broadened our knowledge of planetary system workings, perhaps the most compelling object…
Habitable zone predictions and how to test them
Ramses M. Ramirez, Dorian S. Abbot, Yuka Fujii +11
The habitable zone (HZ) is the region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. The classical HZ definition makes a number of as…
