Magnesium abundance in the Galactic halo stars and subsystem formation history
Data from our compiled catalogue of spectroscopically determined magnesium abundances in dwarfs and subgiants with accurate parallaxes are used to select Galactic halo stars according to kinematic criteria and to identify presumably accreted stars among them. We analyse the relations between the relative magnesium abundances, metallicities and Galactic orbital elements for accreted halo stars.
