Investigating potential causes for high inferred intrinsic temperatures of warm transiting Neptune and Sub-Neptune planets

Saugata Barat, Jean-Michel Désert, Allona Vazan +7

Atmospheric characterization of a warm 10-30 Myr old sub-Neptune progenitor (V1298 Tau b) and a 3.4 Gyr old warm super-Neptune (WASP-107b) using JWST have revealed extremely…

Super-Earth Interiors Shrink by About 10% as They Crystallise

Tim Lichtenberg, Mara Attia, Harrison Nicholls +26

Super-Earth exoplanets are among the most abundant planets known, yet their bulk densities leave the interior state degenerate. The static structure models used to interpret them,…

The Viability of Life in Helium-Dominated Exoplanet Atmospheres

Sara Seager, Janusz J. Petkowski

Helium is the second most abundant element in the Universe, yet helium-dominated atmospheres are rarely considered as environments for life. Two assumptions have contributed to thi…

Ionic Liquid Biospheres

Sara Seager, William Bains, Iaroslav Iakubivskyi +4

Liquid is a fundamental requirement for life as we understand it, but whether that liquid has to be water is not known. We propose the hypothesis that ionic liquids (ILs) and deep…

Warm, water-depleted rocky exoplanets with surface ionic liquids: A proposed class for planetary habitability

Rachana Agrawal, Sara Seager, Iaroslav Iakubivskyi +6

The discovery of thousands of exoplanets and the emergence of telescopes capable of exoplanet atmospheric characterization have intensified the search for habitable worlds. Due to…

Flares on TRAPPIST-1 reveal the spectrum of magnetic features on its surface

Valeriy Vasilyev, Nadiia Kostogryz, Alexander I. Shapiro +11

TRAPPIST-1 is an M8 dwarf hosting seven known exoplanets and is currently one of the most frequently observed targets of the James Webb Space Telescope (JWST). However, it is notor…
