Stellar rotation and activity

Dedicated to an audience of graduate students and early-career researchers, this presentation aims at presenting our current state of knowledge relative to rotation and magnetic activity of solar-type stars in the context of spaceborne photometry. The first part of the presentation is dedicated to presenting observational evidences of rotation and activities in the Sun and other solar-type stars. In the second part, rotation of solar-type stars is put in an evolutionary context while the third part covers the basic knowledge necessary to understand stellar magnetic dynamo. Finally, the fourth part details some findings enabled by large space-borne photometric surveys and the performances that can be expected from the PLATO mission are briefly presented.
