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…
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…
