Multiple stellar populations in Magellanic Clouds clusters. I. An ordinary feature for intermediate age globulars in the LMC?
A. P. Milone, L. R. Bedin, G. Piotto +1
The discovery of multiple MSs in NGC2808 and Omega Centauri, and multiple SGBs in NGC1851 and NGC6388 has challenged the long-held paradigm that GCs consist of simple stellar popul…
MCAO near-IR photometry of the Globular Cluster NGC 6388: MAD observations in crowded fields
A. Moretti, G. Piotto, C. Arcidiacono +15
Deep photometry of crowded fields, such as Galactic Globular Clusters, is severely limited by the actual resolution of ground-based telescopes. On the other hand, the Hubble Space…
The ACS Survey of Galactic Globular Clusters. III. The Double Subgiant Branch of NGC 1851
A. P. Milone, L. R. Bedin, G. Piotto +13
Photometry with HST's ACS reveals that the subgiant branch (SGB) of the globular cluster NGC 1851 splits into two well-defined branches. If the split is due only to an age effect,…
Ground-Based CCD Astrometry with Wide Field Imagers. I. [Observations just a few years apart allow decontamination of field objects from members in two Globular clusters.]
Jay Anderson, Luigi R. Bedin, Giampaolo Piotto +3
This paper is the first of a series of papers in which we will apply the methods we have developed for high-precision astrometry (and photometry) with the Hubble Space Telescope to…
Star-Cluster Astrometry with Ground-Based Wide Field Imagers
L. R. Bedin, J. Anderson, G. Piotto +2
We show the astrometric potential of the Wide Field Imager at the focus of the MPI-ESO 2.2m Telescope. Currently, we are able to measure the position of a well-exposed star with a…
