Climate Transition to Temperate Nightside at High Atmosphere Mass
Evelyn Macdonald, Kristen Menou, Christopher Lee +1
Our recent work shows how M-Earth climates and transmission spectra depend on the amount of ice-free ocean on the planet's dayside and the mass of N2 in its atmosphere. M-Earths wi…
Water Vapour Transit Ambiguities for Habitable M-Earths
Evelyn Macdonald, Kristen Menou, Christopher Lee +1
We have shown in a recent study, using 3D climate simulations, that dayside land cover has a substantial impact on the climate of a synchronously rotating temperate rocky planet su…
Haze optical depth in exoplanet atmospheres varies with rotation rate: Implications for observations
Maureen Cohen, Paul I. Palmer, Adiv Paradise +2
Transmission spectroscopy supports the presence of uncharacterised, light-scattering and -absorbing aerosols in the atmospheres of many exoplanets. The complexity of factors influe…
Sporadic Spin-Orbit Variations in Compact Multi-planet Systems and their Influence on Exoplanet Climate
Howard Chen, Gongjie Li, Adiv Paradise +1
Climate modeling has shown that tidally influenced terrestrial exoplanets, particularly those orbiting M-dwarfs, have unique atmospheric dynamics and surface conditions that may en…
Climate uncertainties caused by unknown land distribution on habitable M-Earths
Evelyn Macdonald, Adiv Paradise, Kristen Menou +1
A planet's surface conditions can significantly impact its climate and habitability. In this study, we use the 3D general circulation model ExoPlaSim to systematically vary dayside…
ExoPlaSim: Extending the Planet Simulator for Exoplanets
Adiv Paradise, Evelyn Macdonald, Kristen Menou +2
The discovery of a large number of terrestrial exoplanets in the habitable zones of their stars, many of which are qualitatively different from Earth, has led to a growing need for…
Fundamental Challenges to Remote Sensing of Exo-Earths
Adiv Paradise, Kristen Menou, Christopher Lee +1
Inferring the climate and surface conditions of terrestrial exoplanets in the habitable zone is a major goal for the field of exoplanet science. This pursuit will require both stat…
A Large Repository of 3D Climate Model Outputs for Community Analysis and Postprocessing
Adiv Paradise, Bo Lin Fan, Evelyn Macdonald +2
As the number of known exoplanets has climbed into the thousands, efforts by theorists to understand the diversity of climates that may exist on terrestrial planets in the habitabl…
Climate Diversity in the Solar-Like Habitable Zone due to Varying Background Gas Pressure
Adiv Paradise, Bo Lin Fan, Kristen Menou +1
A large number of studies have responded to the growing body of confirmed terrestrial habitable zone exoplanets by presenting models of various possible climates. However, the impa…
A Statistical Comparative Planetology Approach to Maximize the Scientific Return of Future Exoplanet Characterization Efforts
Jade H. Checlair, Dorian S. Abbot, Robert J. Webber +37
Provided that sufficient resources are deployed, we can look forward to an extraordinary future in which we will characterize potentially habitable planets. Until now, we have had…
Habitable Snowballs: Temperate Land Conditions, Liquid Water, and Implications for CO Weathering
Adiv Paradise, Kristen Menou, Diana Valencia +1
Habitable planets are commonly imagined to be temperate planets like Earth, with areas of open ocean and warm land. In contrast, planets in snowball states, where oceans are entire…
GCM Simulations of Unstable Climates in the Habitable Zone
Adiv Paradise, Kristen Menou
It has recently been proposed that Earth-like planets in the outer regions of the habitable zone experience unstable climates, repeatedly cycling between glaciated and deglaciated…
A Machine Learns to Predict the Stability of Tightly Packed Planetary Systems
Daniel Tamayo, Ari Silburt, Diana Valencia +9
The requirement that planetary systems be dynamically stable is often used to vet new discoveries or set limits on unconstrained masses or orbital elements. This is typically carri…
