Lee, Hyun-chul; Worthey, G; Dotter, Aaron; Chaboyer, Brian; Jevremovic, Darko; Baron, E; Briley, Michael M; Ferguson, Jason W; Coelho, Paula; Trager, Scott C


The first paper in this series explored the effects of altering the chemical mixture of the stellar population on an element-by-element basis on stellar evolutionary tracks and isochrones to the end of the red giant branch. This paper extends the discussion by incorporating the fully consistent synthetic stellar spectra with those isochrone models in predicting integrated colors, Lick indices, and synthetic spectra. Older populations display element ratio effects in their spectra at higher...[Show more]
