Towards a Solution for the Ca II Triplet Puzzle : Results from Dwarf Elliptical Galaxies
Dolf Michielsen, Mina Koleva, Philippe Prugniel +6
We present new estimates of ages and metallicities, based on FORS/VLT optical (4400-5500A) spectroscopy, of 16 dwarf elliptical galaxies (dE's) in the Fornax Cluster and in Souther…
NBursts: Simultaneous Extraction of Internal Kinematics and Parametrized SFH from Integrated Light Spectra
Igor Chilingarian, Philippe Prugniel, Olga Sil'chenko +1
We present a novel approach for simultaneous extraction of stellar population parameters and internal kinematics from the spectra integrated along a line of sight. We fit a templat…
Analysis of stellar populations with large empirical libraries at high spectral resolution
Philippe Prugniel, Mina Koleva, Pierre Ocvirk +2
The stellar population models dramatically progressed with the arrival of large and complete libraries, ELODIE, CFLIB (=Indo-US) and MILES at a relatively high resolution. We show…
Comparison of different spectral population models
Mina Koleva, Philippe Prugniel, Pierre Ocvirk +3
We have compared simple stellar populations (SSPs) generated with different population synthesis tools: BC03, Vazdekis and Pegase.HR and different stellar libraries: ELODIE3.1, Ste…
New release of the ELODIE library: Version 3.1
Ph. Prugniel, C. Soubiran, M. Koleva +1
We present ELODIE.3.1, an updated release of the library published in Prugniel & Soubiran (2001, 2004). The library includes 1962 spectra of 1388 stars obtained with the ELODIE spe…
Age and metallicity of Galactic clusters from full spectrum fitting
Mina Koleva, Philippe Prugniel, Pierre Ocvirk +1
We are using full spectrum fitting to determine the ages and metallicities of Galactic clusters (M67 and globular clusters). We find that the method is very accurate to measure the…
