Model light curves produced by the tail shown in Fig. 5 at wavelengths of 0.65 μm (solid blue), 0.85 μm (dashed orange) and 2.5 μm (dot-dashed red) compared with the Kepler long-cadence light curve of Kepler-1520 b (black). The model light curves are convolved to the Kepler long-cadence of 30 min. To produce this light curve, meta-particles were ejected with a spherically symmetric distribution from a planet of radius 0.020 R_⊕ and mass 8.4 × 10⁻⁶ M_⊕ with a velocity of 3.0 times theplanet’s surface escape velocity (or 674 m s⁻¹) at a mass-loss rate of 18.8 M_⊕ Gyr⁻¹.
