DOI: 10.1051/0004-6361/201731659
Abstract: We determined abundances of Mg and K in the atmospheres of 53 (Mg) and 75 (K) turn-off (TO) stars of the Galactic globular cluster 47 Tuc. The obtained abundances, together with those of Li, O,… read more here.

DOI: 10.1093/mnras/staa478
Abstract: Studies of the kinematics and chemical compositions of Galactic globular clusters (GCs) enable the reconstruction of the history of star formation, chemical evolution, and mass assembly of the Galaxy. Using the latest data release (DR16)… read more here.

DOI: 10.1093/mnras/stab1475
Abstract: We use the data from Gaia Early Data Release 3 (EDR3) to study the kinematic properties of Milky Way globular clusters. We measure the mean parallaxes and proper motions (PM) for 170 clusters, determine the PM… read more here.

DOI: 10.1093/mnras/stad1066
Abstract: There are primarily two relations currently being used in the literature to calculate the metal abundance of ab-type RR Lyrae variables from their periods and V-band amplitudes. They are the one from Alcock et al., which… read more here.

DOI: 10.1093/mnras/sty2707
Abstract: For a sample of 38 Galactic globular clusters (GCs), we confront the observed distributions of blue straggler (BS) proper motions and masses (derived from isochrone fitting) from the BS catalog of Simunovic & Puzia with… read more here.
