Solar CAII Measurements and Activity Cycles in Solar-Type Stars
Abstract
Measurements of the integrated solar flux in the calcium Kline mode at Sacramento Peak are compared to those made at Kitt Peak. The measurements span about 2 solar cycles. The solar measurements are compared with similar measurements made for Solar-1.Ke stars. We find that compared to other solar-1.Ke stars, that the sun is in a very active cycling state. Stars appear to spend about one-third of their lifetime in non-cycling states such as the Maunder minimum which occurred in the 17th century.
