Magnetic activity evolution of solar-like stars: II. $S_{\mathrm{ph}}$-Ro evolution of Kepler main-sequence targets

Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16

There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index $S_{\mathrm{ph}}$. We use this data, in conjunction w…
