Hubble Space Telescope survey of Magellanic Cloud star clusters. Photometry and astrometry of 113 clusters and early results
A. P. Milone, G. Cordoni, A. F. Marino +29
In the past years, we have undertaken an extensive investigation of LMC and SMC star clusters based on HST data. We present photometry and astrometry of stars in 101 fields observe…
The HST large programme on NGC 6752 -- IV. The White Dwarf Sequence
L. R. Bedin, M. Salaris, J. Anderson +13
We present our final study of the white dwarf cooling sequence (WD CS) in the globular cluster NGC 6752. The investigation is the main goal of a dedicated Hubble Space Telescope la…
Blue Stragglers as tracers of the dynamical state of two clusters in the Small Magellanic Cloud: NGC 339 and NGC 419
Francesca Dresbach, Davide Massari, Barbara Lanzoni +5
The level of central segregation of Blue Straggler stars proved to be an excellent tracer of the dynamical evolution of old star clusters (the so-called "dynamical clock"), both in…
Survey of multiple populations in globular clusters among very low-mass stars
E. Dondoglio, A. P. Milone, A. Renzini +14
Recent work has shown that NIR Hubble Space Telescope (HST) photometry allows us to disentangle multiple populations (MPs) among M dwarfs of globular clusters (GCs) and investigate…
