small molecular feature in the transmission spectrum of WASP-39b at 4.05 m, Aggarwal, Radica, Berta-Thompson, Molaverdikhani, Mukherjee, Laura, Crouzet,最近, Jordan, Feinstein, Zhang, and therefore the detection of other SO2 absorption bands at different wavelengths is needed to better constrain the SO2 abundance. Here we report the detection of SO2 spectral features at 7.7 and 8.5 m in the 512 m transmission spectrum of WASP-39b measured by the JWST Mid-Infrared Instrument (MIRI) Low Resolution Spectrometer (LRS) . Our observations suggest an abundance of SO2 of 0.525 ppm (1 range), Nicolas, compared to that produced from the photochemistry of H2O and H2S (1-10 ppm) . However,SO2的丰度较低(1 ppb),这是由于在热化学平衡下。
Sean, we derive an atmospheric heavy element content (metallicity) for WASP-39b of 7.18.0 solar and demonstrate that photochemistry shapes the spectra of WASP-39b across a broad wavelength range.
