The abundances of 18 cool giant stars in Vicinity of Sun have been determinated. This determination was made by using the method of model atmospheres. It should be noted that almost all elements show discrepancies in abundances determined for absorpt

Based on the spectra obtained with echelle spectrograph SOPHIE (1.93 mtelescope, OHP,France) and the selection of lines (Basak & Mishenina, 2012). we have redefined the parameters and have determined the abundances of the elements produced in the pro

Abundances of neutron-capture (n- capture) elements in the stars belonging to thin and thick disks are obtained. The separation of thin and thick stars on kinematic criterion was made early. The spectra were obtained with the ELODIE spectrograph at t

Using the spectra obtained with echelle spectrograph SOPHIE (1.93 m telescope, OHP, France) and the data from about 20 papers of various authors, we have compiled a list for around four thousand lines of different chemical elements. Based on the spec
