Star Formation History in the Galactic Thin Disk
V. A. Marsakov, M. V. Shapovalov, T. V. Borkova
The behavior of the relative magnesium abundances in the thin-disk stars versus their orbital radii suggests that the star formation rate in the thin disk decreases with increasing…
Stellar Objects of Extragalactic Origin in the Galactic Halo
V. A. Marsakov, T. V. Borkova
We identified globular clusters and field stars of extragalactic origin and investigated their chemical, physical, and kinematical properties. This objects as supposed was captured…
Formation of Galactic Systems in Light of the Magnesium Abundance in Field Stars: The Thin Disk
V. A Marsakov, T. V. Borkova
We analyze the relations between the relative magnesium abundances in stars and their metallicities, Galactic orbital elements, and ages. The relative magnesium abundances in metal…
A Compiled Catalogue of Spectroscopically Determined Elemental Abundances for Stars with Accurate Parallaxes. I.Magnesium
T. V. Borkova, V. A. Marsakov
We present a compiled catalogue of effective temperatures, surface gravities, iron and magnesium abundances, distances, velocity components, and orbital elements for stars in the s…
Stars of extragalactic origin in the solar neighborhood
T. V. Borkova, V. A. Marsakov
We computed the spatial velocities and the galactic orbital elements using Hipparcos data for 77 nearest main-sequence F-G-stars with published the iron, magnesium, and europium ab…
Distant globular clusters with anomalously small masses
T. V. Borkova, V. A. Marsakov
We found that 10 metal-poor globular clusters are greately distinguished for anomalously small masses on the "destruction rate--mass" plain. As it turned out, these poor clusters,…
