On the white dwarf cooling sequence of the globular cluster Omega Centauri
A. Calamida, C. E. Corsi, G. Bono +16
We present deep and precise photometry (F435, F625W, F658N) of Omega Cen collected with the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope (HST). We have ide…
On the radial distribution of white dwarfs in the Galactic globular cluster Omega Cen
A. Calamida, C. E. Corsi, G. Bono +14
We present deep and accurate photometry (F435W, F625W, F658N) of the Galactic Globular Cluster Omega Cen collected with the Advanced Camera for Surveys (ACS) on board the Hubble Sp…
Stroemgren metallicity calibration: the m1, b-y relation
A. Calamida, G. Bono, P. B. Stetson +15
We performed a new calibration of the Stroemgren metallicity index m1 based on the b-y color of cluster red giant stars. The current Metallicity-Index-Color relation is not linear…
Have loose globular clusters collapsed yet?
Guido De Marchi, Francesco Paresce, Luigi Pulone
We report on the discovery of a surprising observed correlation between the slope of the low-mass stellar global mass function (GMF) of globular clusters (GCs) and their central co…
Tidal disruption and the tale of three clusters
Guido De Marchi, Francesco Paresce, Luigi Pulone
How well can we tell whether a globular cluster will survive the Galaxy's tidal forces? This is conceptually easy to do if we know the cluster's total mass, mass structure and spac…
Why haven't loose globular clusters collapsed yet?
Guido De Marchi, Francesco Paresce, Luigi Pulone
We report on the discovery of a surprising observed correlation between the slope of the low-mass stellar global mass function (GMF) of globular clusters (GCs) and their central co…
