Stellar Evolution and The Habitable Zone: Overall Properties and the Impact of Activity and Rotation
M. H. Pinsonneault (Ohio State University)
The impact of stellar properties on the habitable zones around them are discussed. The predicted luminosity as a function of mass, composition, and age is well-constrained. However there is recent data indicating that the radii of lower-mass stars are inconsistent with theoretical predictions. I will present evidence in favor of a significant activity-radius effect as the likely explanation. I will also review effects typically neglected in stellar models, especially rotation and activity, and argue that they can have a significant impact on habitability.
