JWST NIRISS/SOSS data yield a transmission spectrum of the 23 Myr V1298 Tau c showing H2O absorption and an atmospheric metallicity of 14.8^{+56}_{-12} times solar, lower than mature planets of similar mass.
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.
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.
