Description
The dynamo process is believed to drive the magnetic activity of stars
like the Sun that have an outer convection zone. Large spectroscopic
surveys showed that there is a relation between the rotation periods and
the cycle periods: the longer the rotation period is, the longer the
magnetic activity cycle period will be. We present the analysis of F
stars observed by Kepler for which individual p modes have been measure
and with surface rotation periods shorter than 12 days. We defined
magnetic indicators and proxies based on photometric observations to
help characterise the activity levels of the stars. With the Kepler
data, we investigate the existence of stars with cycles (regular or
not), stars with a modulation that could be related to magnetic
activity, and stars that seem to show a flat behaviour.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
