They used NIRSpec G395H to observe the planet during periastron passage to see how the spectrum changes during transit.
They find pre-periapsis phases are consistent with a blackbody due to clouds or just an isothermal profile. Post-periapsis suggests evidence for methane and CO. This all with eq. chemistry without photochem. The lag between Tsai+ and their observations could be due to rotation periods and radiative timescales. They don’t see a temperature inversion. #exoplanets5
