17. SIG: Stellar Spectra Computing The synthetic spectra modeling

18. Within the framework of the BalticGrid project the Stellar Spectroscopy group of the Institute of Theoretical Physics and Astronomy of Vilnius university has upgraded and gridified a program package for the synthetic spectra modeling and is using it for: ■ Chemical analysis of Galactic Red clump stars ■ Chemical analysis of open clusters in the Galactic disk ■ Investigation of chemical evolution of the Galactic thick disk ■ Chemical analysis of stars in neighboring galaxies ■ Analysis of chromospherically active stars

19. The GAIA space observatory will produce a huge amount of data, so we need to be prepared to analyze them. SIG: Stellar Spectra Computing
