POSEIDON now includes lab-derived rocky surface albedos, enabling JWST emission spectra to separate thin versus thick atmospheres and potentially identify granite-like versus basaltic surfaces.
No bursty planet-induced radio emission detected from five inactive M dwarfs; upper limits constrain GJ 367 b magnetosphere to <0.8 G under assumed stellar wind conditions.
Collates archival stellar activity and rotation data for potential HWO targets, finding measurements for at least 70% of high-interest systems but activity cycles for fewer than 20%.
