The solar-stellar connection: new insights from the Kepler mission.
Abstract
Magnetic fields appear to be ubiquitous in almost all types of stars although the underlying generation mechanism can be very different along the HR diagram. For instance, one of the most promising models of the solar activity cycle is based on the idea that the meridional circulation determines the period of the solar cycle if the eddy diffusivity is low enough. On the other hand, in massive stars the possibility of generating a dynamo action in radiative envelopes is still much debated. In this context the high-quality photometric data provided by the Kepler mission provide important information on the possible dynamo actions in young, fast-rotating, solar-type stars.
