Caption: Figure 17.
The period distribution of our Platinum sample, colored by spot filling fraction, and plotted with rotation sequences of benchmark open clusters. In the K temperature range (between 4000 and 4500 K), NGC 6811 and Rup 147 exhibit stalled rotational braking, a departure from current gyrochronological models. The spot filling fractions are elevated here as well.
