Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory

Courtney D. Dressing, Danica Adams, Evelyne Alecian +324

The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…

Coupled Photochemical-Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets

Megan Gialluca, Victoria Meadows, Andrew Lincowski +4

Available JWST observations TRAPPIST-1 system have suggested that several of the planets are likely airless, or possess a very tenuous atmosphere. However, the high atmospheric esc…

The Range of Cumulative XUV Flux on GJ 1132 b

Rory Barnes, Laura N. R. do Amaral, Jessica Birky +4

We investigate the plausible history of the XUV luminosity evolution of the planet-hosting M4 star GJ 1132 (~0.2 solar masses) to infer the cumulative incident XUV flux intercepted…

Investigation of Venus' thermal history, crustal evolution, and core dynamics with a coupled interior-lithosphere-atmosphere model

Rodolfo Garcia, Rory Barnes, Peter E. Driscoll +2

We simulate Venus' evolution with a coupled one-dimensional solar-atmosphere-lithosphere-mantle-core model to predict currently unobservable features and its eruptive mass flux. We…

Shedding Light on Large Space-Based Telescopes: Modeling Stray Light due to Primary Mirror Damage from Micrometeoroid Impacts

Megan T. Gialluca, Jonathan W. Arenberg, Chris Stark +5

A large space-based telescope aimed at detecting and characterizing the atmospheres of Earth-like planets orbiting Sun-like stars will require unprecedented contrast and stability.…

Statistical geochemical constraints on present-day water outgassing as a source of secondary atmospheres on the TRAPPIST-1 exoplanets

Trent B. Thomas, Victoria S. Meadows, Joshua Krissansen-Totton +3

The TRAPPIST-1 planetary system is observationally favorable for studying if planets orbiting M stars can retain atmospheres and host habitable conditions. Recent JWST secondary ec…

History and Habitability of the LP 890-9 Planetary System

Rory Barnes, Laura N. R. do Amaral, Jessica Birky +42

We present numerous aspects of the evolution of the LP 890-9 (SPECULOOS-2/TOI-4306) planetary system, focusing on the likelihood that planet c can support life. We find that the ho…

Properties of outer solar system pebbles during planetesimal formation from meteor observations

Peter Jenniskens, Paul R. Estrada, Stuart Pilorz +42

In the late stages of accretion leading up to the formation of planetesimals, particles grew to pebbles the size of 1-mm to tens of cm. That is the same size range that dominates t…

The Implications of Thermal Hydrodynamic Atmospheric Escape on the TRAPPIST-1 Planets

Megan T. Gialluca, Rory Barnes, Victoria S. Meadows +3

JWST observations of the 7-planet TRAPPIST-1 system will provide an excellent opportunity to test outcomes of stellar-driven evolution of terrestrial planetary atmospheres, includi…

Characterizing Atmospheres of Transiting Earth-like Exoplanets Orbiting M Dwarfs with James Webb Space Telescope

Megan T. Gialluca, Tyler D. Robinson, Sarah Rugheimer +1

A number of transiting, potentially habitable Earth-sized exoplanets have recently been detected around several nearby M dwarf stars. These worlds represent important targets for a…

Velocity Dispersion of the GD-1 Stellar Stream

Megan T. Gialluca, Rohan P. Naidu, Ana Bonaca

Tidally dissolved globular clusters form thin stellar streams that preserve a historical record of their past evolution. We report a radial velocity dispersion of $2.3\pm0.3\,\text…
