Query: L 98-59: a Benchmark System of Small Planets for Future Atmospheric
  Characterization   L 98-59 is an M3V dwarf star that hosts three small (R < 1.6 Earth radii)
planets. The host star is bright (K = 7.1) and nearby (10.6 pc), making the
system a prime target for follow-up characterization with the Hubble Space
Telescope (HST) and the upcoming James Webb Space Telescope (JWST). Herein, we
use simulated transmission spectroscopy to evaluate the detectability of
spectral features with HST and JWST assuming diverse atmospheric scenarios
(e.g., atmospheres dominated by H2, H2O, CO2, or O2). We find that H2O and CH4
present in a low mean-molecular weight atmosphere could be detected with HST in
1 transit for the two outermost planets, while H2O in a clear steam atmosphere
could be detected in 6 transits or fewer with HST for all three planets. We
predict that observations using JWST/NIRISS would be capable of detecting a
clear steam atmosphere in 1 transit for each planet, and H2O absorption in a
hazy steam atmosphere in 2 transits or less. In a clear, desiccated atmosphere,
O2 absorption may be detectable for all three planets with NIRISS. If the L
98-59 planets possess a clear, Venus-like atmosphere, NIRSpec could detect CO2
within 26 transits for each planet, but the presence of H2SO4 clouds would
significantly suppress CO2 absorption. The L 98-59 system is an excellent
laboratory for comparative planetary studies of transiting multiplanet systems,
and observations of the system via HST and JWST would present a unique
opportunity to test the accuracy of the models presented in this study.
