Stellar Analogs of Solar Activity.
Abstract
A fiber-coupled spectrograph (FSC) for moderate-resolution stellar observations has been designed, fabricated, and tested. The excellent short- and long-term stability of this instrument represents a significant advance in the state-of-the-art for high precision stellar spectrophotometry. A preliminary observational survey of the greatly enhanced analogs of solar activity that exist in flare stars and the RS CVn binaries has been performed using this instrument, and the starspot model for explaining the photometric variability of these latter stars has been verified spectroscopically.
