Age-Divided Mean Stellar Populations from Full Spectrum Fitting as the Simplified Star Formation and Chemical Evolution History of a Galaxy: Methodology and Reliability
Abstract:We introduce a practical methodology for investigating the star formation and chemical evolution history of a galaxy: age-divided mean stellar populations (ADPs) from full spectrum fitting. In this method, the mass-weighted mean stellar populations and mass fractions ( mass ) of young and old stellar components in a galaxy are separately estimated, which are divided with an age cut (selected to be 10 9.5 yr ≈ 3.2 Gyr in this paper). To examine the statistical reliability of ADPs, we generate 10,000 artificial … Show more
