Confirmation of Subsolar Metallicity for WASP-77Ab from JWST Thermal Emission Spectroscopy
We present the dayside thermal emission spectrum of WASP-77Ab from 2.8 to 5.2 μ m as observed with the NIRSpec instrument on the James Webb Space Telescope (JWST). WASP-77Ab was previously found to have a subsolar metallicity and a solar carbon-to-oxygen (C/O) ratio from H _2 O and CO absorption lin...
