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 initial spin distribution of B-type stars revealed by the split main sequences of young star clusters
Chen Wang, Ben Hastings, Abel Schootemeijer +6
Spectroscopic observations of stars in young open clusters have revealed evidence for a dichotomous distribution of stellar rotational velocities, with 10-30% of stars rotating slo…
The chemical compositions of multiple stellar populations in the globular cluster NGC 2808
M. Carlos, A. F. Marino, A. P. Milone +8
Pseudo two-colour diagrams or Chromosome maps (ChM) indicate that NGC 2808 host five different stellar populations. The existing ChMs have been derived by the Hubble Space Telescop…
Transmission curves of narrow-band filters in large-FoV and fast astronomical instruments
Federico Battaini, Roberto Ragazzoni, Antonino P. Milone +1
Narrow-band filters are often used to constrain the chemical composition of astronomical objects through photometry. A challenge to derive accurate photometry is that narrow-band f…
Chromosome maps of Globular Clusters from wide-field ground-based photometry
S. Jang, A. P. Milone, M. V. Legnardi +10
Hubble Space Telescope (HST) photometry is providing an extensive analysis of globular clusters (GCs). In particular, the pseudo two-colour diagram dubbed 'chromosome map (ChM)' al…
NGC1818 unveils the origin of the extended main-sequence turn-off in young Magellanic Clouds clusters
Giacomo Cordoni, Antonino P. Milone, Anna F. Marino +8
The origin of young star clusters represents a major challenge for modern stellar astrophysics. While stellar rotation partially explains the colour spread observed along main-sequ…
