Abstract

In the previous chapter we discussed the various aspects of stellar activity. In this chapter we will outline the underlying theoretical background that explains stellar activity as well as the stellar activity cycle. This theory is based on the stellar dynamo, similar to the solar dynamo. We will see that the rotation of a star is a crucial parameter for understanding stellar dynamos.
