Chemistry, Climate, And Transmission Spectra Of TRAPPIST-1 e Explored With A Multimodel Sparse Sampled Ensemble
TRAPPIST-1 e is one of a few habitable zone exoplanets that is amenable to characterization in the near term. In this study our motivations are both scientific and technical.
Near The Runaway: The Climate And Habitability Of Teegarden’s Star b
Teegarden’s Star b, a nearby terrestrial world receiving an Earth-like instellation, is a prime candidate for next-generation observatories targeting temperate exoplanets in their habitable zones.
Born Dry or Born Wet? A Palette of Water Growth Histories in TRAPPIST-1 Analogs and Compact Planetary Systems
It is still unclear whether exoplanets in compact multiplanet systems such as TRAPPIST-1 are able to accrete large quantities of volatiles, grow to sufficient mass, and maintain robust atmospheres and […]
JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e
The TRAPPIST-1 system offers one of the best opportunities to characterize temperate terrestrial planets beyond our own solar system.
Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics
In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations.
Exploring Stellar Activity In A Sample Of Active M Dwarfs
Most M dwarfs show higher chromospheric activity, often exceeding solar levels. Characterizing stellar activity is essential, particularly since these stars are prime targets in the search for habitable exoplanets.
The Next Big Thing: The Habitable Worlds Observatory and Inaugural HWO25 Conference
The Habitable Worlds Observatory (HWO) is NASA’s next flagship observatory for the 2030s, following its top rank for large space projects in the Astro2020 decadal survey. With transformative ultraviolet, optical, […]
Earth’s Oxygen Boom: A Fresh Perspective For A Billion-year-old Problem
The appearance of oxygen in Earth’s atmosphere was a turning point in the history of our planet, forever transforming the environment and setting the stage for complex life. This event, […]
Special Issue of Geosciences: “Worlds of the Solar System: Geological Evolution and Habitability of Planets and Moons”
The Special Issue of Geosciences entitled “Worlds of the Solar System: Geological Evolution and Habitability of Planets and Moons” aims to bring together the latest advances on the dynamic processes […]
