The Long and the Short of It: Timescales for Stellar Activity
Stellar activity varies on a range of timescales, from the long-term decrease due to stellar spindown, through the shorter timescales of magnetic cycles and the rapid fluctuations of flares and coronal mass ejections. All of these are influenced by the mass of the star. This governs the nature of the dynamo that generates magnetic field in the stellar interior and determines the observed large-scale magnetic structure. Stellar mass also governs the processes (such as differential rotation) that transport flux across stellar surfaces and drive coronal evolution and dynamics. In this talk I will review recent progress in these areas and consider the impact that stellar activity on all these timescales may have on exoplanetary systems.
