Light curve of a star moving at 500 km s⁻¹ along the track shown in Figure 12. The blue dotted line corresponds to a star with the same diameter as the pixel of the simulation (320 R_⊙), while the red solid line corresponds to a much larger and more luminous star with R = 1500 R_⊙. The star crosses the entire caustic region in ∼9 yr, with the first peak grazing the caustic and producing a wide peak.
