Rationale

Kepler space telescope provides a large volume of stellar light curves, from which the magnetic activity properties of the solar-type stars in the Kepler field can be obtained. The magnetic activity information can be derived from a light curve through the light-curve fluctuation, the flare spikes in the light curve, as well as the asteroseismology techniques. More magnetic activity information can be provided by the supplementary observations of the ground-based telescopes. Owing to the large sample of solar-type stars in Kepler targets and the continuous observation of light curves, new insights on the magnetic activities of solar-type stars are expected from the Kepler observations, which will be discussed in this focus meeting. The results of stellar magnetic activities from other space and ground telescopes are also welcome. Special interests are on the solar-stellar connection and the influence of stellar activity on the planetary habitability.
