Abstract

Attempts to understand solar change and its influence on the earth are frustrated by the brevity of our life spans. The few decades of modern solar-terrestrial data hint at secular modifications, but we can only speculate what the sun has in store for us and on what time scale. Yet the sky abounds with stars similar to the sun—some older, some younger—and through these living examples, we ought to be able to look into the future and past. This workshop assessed the technology for observing such solar-type stars (by means of precision stellar spectroscopy and photometry), considered the available evidence, and inquired as to what questions needed answers in order for scientists to decide between various proposed theoretical models of stellar/solar activity mechanisms.
