JWST-TST DREAMS: Sulfur Dioxide in the Atmosphere of the Neptune-mass Planet HAT-P-26 b from NIRSpec G395H Transmission Spectroscopy

We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 M _⊕ , 6.33 R _⊕ ), based on a single transit observed with the JWST NIRSpec G395H grating. We detect water vapor ( ${\mathrm{ln}}\,{ \mathcal B }$ = 4.1), carbon dioxide ( ${\mathrm{ln}}\,{ \mat...
