[80.17] The Solar-Stellar Spectrograph: Unification of Solar and Stellar Flux Scales and Initial Results

Jeffrey C. Hall, G.W.Lockwood (Lowell Observatory), Erika L. Gibb (Northern AZ Univ)

We present the science results from the first two years of the Solar-Stellar Spectrograph (SSS) project. These results will include (1) representative observations from our current database of $\approx 1500$ spectra of about 200 solarlike stars, (2) a discussion of their calibration to flux, (3) our initial detections of cyclic as well as shorter-term variability, (4) variability correlations between various diagnostic lines, (5) the unification of our flux-calibrated data to all extant datasets, in particular the Mt.\ Wilson $S$ index, and (6) the consistent placement of the Sun among the stellar sample.
