In order to further improve the fit on the lightcurve shoulders it was necessary to introduce two starspots on the secondary and the combined effect can be seen in Figure 5 when compared with Figure 4.
They are following up with further ground-based observations and intend to model the lightcurves to establish the parameters of the binary system and its starspot properties.
When a starspot rotates into view, it can confound spectroscopic measurements.

But before the team could celebrate clear skies on the exo-Neptune, they had to show that starspots -- cooler "freckles" on the face of stars -- were not the real sources of water vapor.
