Stellar populations and their kinematics from high and medium resolution spectra: mixed inversions
Abstract
We present inversion techniques aiming at recovering the stellar content (age, metallicity, extinction) and kinematics of a stellar population from its absorption line spectrum. These techniques use new synthetic high resolution spectra produced by PEGASEHR and minimization algorithms. Application to SDSS data and to a simulated disc-bulge system are presented as examples.
