Caption: Figure 7.
Examples of hypothetical spot distributions with ∼40% spot coverage and ∼1.4% rotational variability in the TESS bandpass. The left panel provides an example of densely filled latitudinal spot bands in which overdensities of spots lead to rotational variability and apparent spot-crossing events, while the right shows large, nonvariable polar spots with a few additional spots that produce the variability and occasional spot-crossing event. The region occulted by HD 189733 b is outlined by dotted white lines in both panels. Made with spotter (Garcia & Rackham 2023).
