On distinguishing age from metallicity with photometric data.

TANG B. and WORTHEY G.

Abstract (from CDS):

In the study of galaxy integrated light, if photometric indicators could extract age and metallicity information of high enough quality, photometry might be vastly more efficient than spectroscopy for the same astrophysical goals. Towards this end, we search three photometric systems: David Dunlap Observatory, Beijing-Arizona-Taiwan-Connecticut and Strömgren systems for their ability to disentangle age and abundance effects. Only the Strömgren [c1] versus [m1] plot shows moderate age-metallicity disentanglement. We also add to the discussion of optical to near-infrared Johnson-Cousins broad-band colours, finding a great decrease in age sensitivity when updated isochrones are used.
