A transmission spectrum contains contributions from a planet's morning and evening limbs, which can differ in temperature, composition and aerosol properties due to atmospheric circulation. While high-resolution ground-based observations have identified limb asymmetry in several ultra-hot/hot exoplanets, space-based studies of limb asymmetry are still in their early stages. The prevalence of limb asymmetry across a broad range of exoplanets remains largely unexplored.
