![]() ![]() ![]() The rectangular coordinates of 407 of the RR Lyrae variables and the components of the three-dimensional (3D) velocities of 401 of the stars are calculated using data from several sources. An analysis of the deviations in the published relative abundances in each star from the mean square values calculated from them reveals an absence of systematic biases among the results from the various articles. The mean weighted chemical abundances are calculated with coefficients inversely proportional to the reported errors. The data from different sources are reduced to a single solar abundance scale. Spectroscopic determinations of the relative abundances of 13 chemical elements in 101 of the RR Lyrae variables are collected from 25 papers published between 19. V.Ī catalog of the chemical and spatial-kinematic parameters of 415 RR Lyrae variables (Lyrids) in the galactic field is compiled. Abundance of Chemical Elements in RR Lyrae Variables and their Kinematic Parameters ![]()
