Left: emitted light spectral energy distribution λL_p,em,λ (Eq. (37)) of our HD 189733b simulation phase curves between 0.3 μm (colour bar: dark purple) to 5.0 μm (colour bar: dark red). Infrared wavelengths from 3−5 μm dominate the emission luminosity at all phases. Right: normalised (to maximum λL_p,em,λ) spectral energy distribution phase curves to emphasise the phase curve shapes. All wavelengths show a α≥ 10° eastward offset from the sub-stellar point.
