Methane on the temperate exo-Saturn TOI-199b
Aaron Bello-Arufe, Renyu Hu, Mantas Zilinskas +10
The authors present a JWST NIRSpec transmission spectrum of the temperate exo‑Saturn TOI‑199b, detecting methane and suggesting the presence of ammonia, while evaluating cloud/haze…
Phase-dependent chemistry of WASP-43 b revealed with a suite of one-, two-, and three-dimensional models
Robin Baeyens, Julianne I. Moses, Jasmina Blecic +17
Our goal is to investigate the chemistry of the hot Jupiter WASP-43 b in detail using theoretical models, considering the constraints of the James Webb Space Telescope MIRI phase c…
C, N, O, S, and photochemistry in a temperate giant planet orbiting a late M dwarf
Michael Zhang, Qiao Xue, Jeehyun Yang +20
We report the JWST NIRSpec/PRISM transit spectrum of TOI-6894b, an exceptional 420 K sub-Saturn that is the only known giant planet transiting a late M dwarf. Remarkably, both the…
Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres
Jeehyun Yang, Vighnesh Nagpal, Michael Zhang +15
Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in…
Sub-Neptunes as Soot Factories: Deep Atmosphere Hydrocarbon Formation and Quenching as the Origin of Sub-Neptune Aerosol Trends
Jeehyun Yang, Eliza M. -R. Kempton, Arjun B. Savel
Recent population-level studies of sub-Neptune atmospheres have identified a tentative parabolic trend in transmission spectrum amplitude for planets with Teq ~ 500-800 K. While th…
Novel Chemical Pathways for the Formation of Nucleobase Precursors via Benzene Ï-Bond Addition to HCN
Jeehyun Yang, Danica J. Adams, Renyu Hu +1
We propose a simple and efficient pathway for the formation of precursors to core nucleobases in DNA and RNA using a suite of computational chemistry methods. Benzene, which is the…
