An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley

Barron K. Nguyen, Laura K. Schaefer, Xuan Ji +7

Recent JWST observations challenge the traditional 'cosmic shoreline' from both sides, revealing thick volatile atmospheres on the hottest close-in 'lava worlds,' where irradiation…

Evidence for an Atmosphere on the Ultra-Short Period super-Earth HD 3167 b

Brandon Park Coy, Qiao Xue, Megan Weiner Mansfield +14

'Lava worlds'-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characteriza…

The JWST Rocky Worlds DDT Program reveals GJ 3929b to likely be a bare rock

Qiao Xue, Michael Zhang, Brandon P. Coy +14

We report first results from the JWST Rocky Worlds Director's Discretionary Time program. Two secondary eclipses of the terrestrial exoplanet GJ 3929b were recently observed using…

The Cosmic Shoreline Revisited: A Metric for Atmospheric Retention Informed by Hydrodynamic Escape

Xuan Ji, Richard D. Chatterjee, Brandon Park Coy +1

The "cosmic shoreline," a semi-empirical relation that separates airless worlds from worlds with atmospheres as proposed by K. J. Zahnle & D. C. Catling, is now guiding large-scale…

Clouds and Seasonality on Terrestrial Planets with Varying Rotation Rates

Daniel A. Williams, Xuan Ji, Paul Corlies +1

Using an idealised climate model incorporating seasonal forcing, we investigate the impact of rotation rate on the abundance of clouds on an Earth-like aquaplanet, and the resultin…
