Comparison of different spectral population models
Published online by Cambridge University Press: 01 December 2006
Abstract
We have compared simple stellar populations (SSPs) generated with different population synthesis tools: BC03, Vazdekis and Pégase.HR and different stellar libraries: ELODIE3.1, SteLib and MILES. We find that BC03/SteLib SSPs are biased toward solar metallicity, however Pégase.HR/ELODIE3.1 and Vazdekis/MILES are extremely consistent. The extensive coverage of the space of atmospheric parameters in the large stellar libraries allows precise synthesis for a large range of ages (0.1 .. 10 Gyr) and metallicities (−2 .. +0.4 dex) limited by the quality of the determination of stellar parameters (temperature scale of the giants).
