The magnetic activity level of low-mass stars is known to vary as a functionof the physical properties of the star. Many studies have shown that thestellar mass and rotation are both important parameters that determine magneticactivity levels. In contrast, the impact of a star's chemical composition onmagnetic activity has received comparatively little attention. Data sets fortraditional activity proxies, e.g. X-ray emission or calcium emission, are notlarge enough to search for metallicity trends in a statistically meaningfulway. Recently, studies have used the photometric variability amplitude as aproxy for magnetic activity to investigate the role of metallicity because itcan be relatively easily measured for large samples of stars. These studiesfind that magnetic activity and metallicity are positively correlated. In thiswork, we investigate the link between activity and metallicity further bystudying the flaring properties of stars in the Kepler field. Similar to thephotometric variability, we find that flaring activity is stronger in moremetal-rich stars for a fixed mass and rotation period. This result adds to agrowing body of evidence that magnetic field generation is correlated withmetallicity.
