Synthetic emission spectra for an atmosphere of increased metallicity. The main cases (in blue and pink) represent models with solar metallicity at two different orbital distances (0.015 and 0.03 AU). For each orbit, atmospheres of 10, 100, and 1000 times metallicity are shown. Some of the contributing opacities are shown for their respective wavelengths. The inset displays the corresponding temperature profiles. The metallicity here does not control the abundance of outgassed silicates or oxygen. Spectra are shown at a resolution of λ/∆λ = 600.
