Different sodium enhancements among multiple populations of Milky Way globular clusters
(EDP Sciences, 2020-11)
We searched for clues to understand the different Na abundances measured in first and second generation stars of ancient Milky Way globular clusters. For that purpose, from the recent literature, we gathered the aforementioned ...
Discovery of rotation axis alignments in Milky Way globular clusters
(EDP Sciences, 2020-06-25)
There is an increasing number of recent observational results that show that some globular clusters exhibit internal rotation while they travel along their orbital trajectories around the Milky Way center. Based on these ...
Washington CCD Photometry of the Globular Cluster System of the Giant Elliptical Galaxy M60 in Virgo
(2008)
We present a photometric study of the globular clusters in the giant elliptical galaxy M60 in the Virgo cluster, based on deep, relatively wide field Washington CT_1 CCD images. The color-magnitude diagram reveals a ...
The search for extratidal star candidates around Galactic globular clusters NGC 2808, NGC 6266, and NGC 6397 with Gaia DR2 astrometry
(EDP Sciences, 2021-01)
Context. Extratidal stars are stellar bodies that end up outside the tidal radius of a cluster as a result of internal processes or external forces acting upon it. The presence and spatial distribution of these stars can ...
