Mantle Convection and Nightside Volcanism on Lava World K2-141 b
Tobias G. Meier, Claire Marie Guimond, Raymond T. Pierrehumbert +13
Ultra-short period lava worlds offer a unique window into the coupled evolution of planetary interior and atmospheres under extreme irradiation. In this study, we investigate the m…
JWST NIRSpec finds no clear signs of an atmosphere on TOI-1685 b
Chloe E. Fisher, Matthew J. Hooton, Amélie Gressier +21
Determining the prevalence of atmospheres on terrestrial planets is a core objective in exoplanetary science. While M dwarf systems offer a promising opportunity, conclusive observ…
Volatile-rich evolution of molten super-Earth L 98-59 d
Harrison Nicholls, Tim Lichtenberg, Richard D. Chatterjee +3
Small low-density exoplanets are sculpted by strong stellar irradiation, but their primordial compositions and subsequent evolution are still unknown. Two often-considered scenario…
JWST NIRISS Transmission Spectroscopy of the Super-Earth GJ 357b, a Favourable Target for Atmospheric Retention
Jake Taylor, Michael Radica, Richard D. Chatterjee +18
We present a JWST NIRISS/SOSS transmission spectrum of the super-Earth GJ 357 b: the first atmospheric observation of this exoplanet. Despite missing the first 40 % of the tr…
Self-limited tidal heating and prolonged magma oceans in the L 98-59 system
Harrison Nicholls, Claire Marie Guimond, Hamish C. F. C. Hay +3
Rocky exoplanets accessible to characterisation often lie on close-in orbits where tidal heating within their interiors is significant, with the L 98-59 planetary system being a pr…
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…
Novel Physics of Escaping Secondary Atmospheres May Shape the Cosmic Shoreline
Richard D. Chatterjee, Raymond T. Pierrehumbert
Recent James Webb Space Telescope observations of cool, rocky exoplanets reveal a probable lack of thick atmospheres, suggesting prevalent escape of the secondary atmospheres forme…
