TRAPPIST-1 flares follow a single power law N(≥E_TESS) ∝ E_TESS^{-0.753} from 10^{29} to 10^{33} erg after sensitivity corrections and bandpass conversion.
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.
Accounting for stellar and orbital uncertainties shows that predicted eclipse depths for bare-rock models of rocky exoplanets carry substantial uncertainty comparable to measurements, establishing a fundamental precision limit for atmospheric and compositional inferences.
The transmission spectrum of AU Mic b is dominated by the transit light source effect from stellar spots, yielding only weak atmospheric constraints with a preferred scale height below 185 km.
WASP-96b shows super-solar metallicity of 2-6x stellar, roughly stellar C/O, tentative SO2 consistent with photochemistry, and an optical slope from scattering aerosols, supporting core-accretion formation beyond the water snowline.
Pandora simulations recover stellar photospheric temperatures to ~30 K with no bias and reduce simple spot contamination from 100-1000 ppm to under 10 ppm, but complex spot geometries leave ~1000 ppm residuals.
Proposes a two-generation Nautilus observatory program using time-series spectroscopy of transiting systems and stellar monitoring to benchmark models of stellar photospheric heterogeneities for exoplanet transmission spectroscopy.
Complete four-observation JWST dataset for GJ 3929 b yields 118±22 ppm eclipse depth, consistent with bare rock while allowing thin atmospheres and ruling out only thick CO2 cases at >3σ.
TOI-159 b is confirmed as the hottest known eccentric hot Jupiter (e = 0.24) with a 13-sigma Keplerian detection around a young gamma Doradus star, including a preliminary low-resolution transmission spectrum.
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%.
