Fraction of flaring stars as a function of their gyrochronology ages for 27,127 stars in six bins of g − i color. The number of stars within each color bin is noted in the legend. Each star has a rotation period determined by McQuillan et al. (2014) and had artificial flare injection tests run by Davenport (2016a). Flaring stars were selected here as having at least three flare events above the 68% recovery completeness threshold in Davenport (2016a). We find a trend of increasing total fraction of active flare stars, and an increasing apparent lifetime for flare activity, with decreasing mass (redder stars).
