Radial variation of the stellar mass functions in the globular clusters M15 and M30: clues of a non-standard IMF?
Mario Cadelano, Emanuele Dalessandro, Jeremy J. Webb +5
We exploit a combination of high-resolution Hubble Space Telescope and wide-field ESO-VLT observations to study the slope of the global mass function (alphaG) and its radial variat…
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…
Substructure in the Globular Cluster Populations of the Virgo Cluster Elliptical Galaxies M84 and M86
Ryan A. Lambert, Katherine L. Rhode, Enrico Vesperini
We have carried out a search for substructure within the globular cluster systems of M84 (NGC 4374) and M86 (NGC 4406), two giant elliptical galaxies in the Virgo Cluster. We use w…
Internal Kinematics of M10 and M71
N. A. Barth, J. M. Gerber, O. M. Boberg +2
We present a study of the internal kinematics of two globular clusters, M10 (NGC 6254) and M71 (NGC 6838), using individual radial velocity (RV) measurements obtained from observat…
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…
Identifying Multiple Populations in M71 Using CN
Jeffrey M. Gerber, Eileen D. Friel, Enrico Vesperini
We have observed the CN features at 3800 ~Å~ and 4120~ Å~ as well as the CH band at 4300~Å~ for 145 evolved stars in the Galactic globular cluster M71 using the multi-o…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XX. Ages of single and multiple stellar populations in seven bulge globular clusters
R. A. P. Oliveira, S. O. Souza, L. O. Kerber +23
In the present work we analyzed seven globular clusters selected from their location in the Galactic bulge and with metallicity values in the range $-1.30\lesssim\rm{[Fe/H]}\lesssi…
