Evolution of Solar-Type Activity: An Observational and Theoretical Perspective
Abstract
When stars depart from the main-sequence, various changes occur including the loss of angular momentum owing to changes in the stellar interior and the impact of stellar winds. These processes affect the amount of outer atmospheric heating and emission as revealed by observations in the UV and X-ray spectral regimes. From a theoretical perspective, both magnetic and acoustic energy generation are affected as indicated by detailed theoretical simulations. Here, I will summarize selected observational and theoretical results, including recent work for Beta Hydri (G2~IV), a star constituting a prime example and proxy for the future Sun.
