Description

Is spotted, that the radial allocations of the abundances of light elements and elements of Ferrum group have bimodal character at the area of distances 4000-10000 pc from the Sun. The transferring of allocation of the metallicity from area 10000 pc in area of major galacto-centric distances has graduated character. For the first time two-dimensional pattern of alloca-tion of the metallicity in the disk on heliocentric distances up to several thousand parsec is con-structed. The behavior of fundamental parameters of cepheid variables is investigated depending on a pulsation phase.
