Abstract

During the large sample survey of LAMOST, mass spectrum of stars was obtained. The analysis of physical parameters, chemical composition and motion track can help us understand more about the structure and evolution of the Milky Way. Based on the investigation and research done on libraries of stellar spectra issued(such as in CDS), here I give an overview of the current status of empirical stellar libraries. I classify the valuable data according to specific criterion, such as spectral coverage/domain and resolution. After the integration of these spectrum, we will finally construct our own library of observed stellar spectra for LAMOST, which will serve as reference for the classification and automatic parameter analysis of stars, as well as for study of the galaxies evolution.
