Multiple stellar populations along the red Horizontal Branch and Red Clump of Globular Clusters

Emanuele Dondoglio, Antonino P. Milone, Edoardo P. Lagioia +5

We exploit multi-band Hubble Space Telescope photometry to investigate multiple populations (MPs) along the red horizontal branches (HBs) and red clumps of fourteen metal-rich Glob…

Exploring the Galaxy's halo and very metal-weak thick disk with SkyMapper and Gaia DR2

G. Cordoni, G. S. Da Costa, D. Yong +16

In this work we combine spectroscopic information from the \textit{SkyMapper survey for Extremely Metal-Poor stars} and astrometry from Gaia DR2 to investigate the kinematics of a…

Mass loss along the red giant branch in 46 Globular Clusters and their multiple populations

M. Tailo, A. P. Milone, E. P. Lagioia +7

The location of Galactic Globular Clusters' (GC) stars on the horizontal branch (HB) should mainly depend on GC metallicity, the "first parameter", but it is actually the result of…

Gaia and Hubble unveil the kinematics of stellar populations in the Type II globular clusters ω Centauri and M 22

G. Cordoni, A. P. Milone, A. F. Marino +8

The origin of multiple stellar populations in Globular Clusters (GCs) is one of the greatest mysteries of modern stellar astrophysics. N-body simulations suggest that the present-d…

A chromosome map to unveil stellar populations with different magnesium abundances. The case of Omega Centauri

A. P. Milone, A. F. Marino, A. Renzini +7

Historically, photometry has been largely used to identify stellar populations (MPs) in Globular Clusters (GCs) by using diagrams that are based on colours and magnitudes that are…

The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XXI. Binaries among multiple stellar populations

A. P. Milone, E. Vesperini, A. F. Marino +17

A number of scenarios for the formation of multiple populations in globular clusters (GCs) predict that second generation (2G) stars form in a compact and dense subsystem embedded…
