Characterising the long-term evolution of magnetic activity on Sun-like stars is important not only for stellar physics but also for understanding the environment in which planets evolve. In the past decades, many photometric surveys of open clusters have produced extensive rotation period measurements on Sun-like stars of different ages. I use these data to infer the long-term evolution of Ca II chromospheric and X-ray coronal emission on solar mass stars combining a best fit parametric model of their rotation evolution with empirical rotation-activity relationships.
