Flux-calibrated stellar population models of Lick absorption-line indices with variable element abundance ratios
Flux-calibrated stellar population models Lick absorption-line indices
2010/10/30
We present new stellar population models of Lick absorption-line indices with variable element abundance ratios. The models are based on our new calibrations of absorption-line indices with stellar pa...
