Fig. 5


Comparison of observations with model (A). Each row corresponds to one of the 800-, 1520-, 1540-, and 1570-day features. Left column: the observations (red/solid line) and model (A) (green/dashed). The fits may not be perfect but the main morphological features are represented. Right column: the cloud of particles (dots) and its parent body (solid line) orbiting the star. Different colors are used to plot particles at different times separated by 25-day intervals. A small number of particles may suffer from close encounters and were thrown into chaotic orbits.
