On a new method to estimate distance, reddening and metallicity of RR Lyrae stars using optical/near-infrared (,,,,,) mean magnitudes: Centauri as a first test case
G. Bono, G. Iannicola, V. F. Braga +26
We developed a new approach to provide accurate estimates of metal content, reddening and true distance modulus of RR Lyrae stars (RRLs). The method is based on homogeneous optical…
On the absolute age of the metal-rich globular M71 (NGC 6838): I. optical photometry
Alessandra Di Cecco, Giuseppe Bono, Pier Giorgio Prada Moroni +9
We investigated the absolute age of the Galactic globular cluster M71 (NGC 6838) by using optical ground-based images (u',g',r',i',z') collected with the MegaCam camera at the Cana…
Optical and Near-Infrared UBVRIJHK Photometry for the RR Lyrae stars in the Nearby Globular Cluster M4 (NGC 6121)
P. B. Stetson, V. F. Braga, M. Dall'Ora +6
We present optical and near-infrared UBVRIJHK photometry of stars in the Galactic globular cluster M4 (NGC 6121) based upon a large corpus of observations obtained mainly from publ…
First Detection of the White-Dwarf Cooling Sequence of the Galactic Bulge
A. Calamida, K. C. Sahu, J. Anderson +13
We present Hubble Space Telescope data of the low-reddening Sagittarius window in the Galactic bulge. The Sagittarius Window Eclipsing Extrasolar Planet Search field (3'x3'), toget…
The halo+cluster system of the Galactic globular cluster NGC1851
A. F. Marino, A. P. Milone, D. Yong +17
NGC1851 is surrounded by a stellar component that extends more than ten times beyond the tidal radius. Although the nature of this stellar structure is not known, it has been sugge…
The globular cluster NGC 6528 the ferrous side of the Galactic Bulge
E. P. Lagioia, A. P. Milone, G. Bono +12
We present new and accurate optical photometry of the Bulge globular cluster NGC 6528. The images were collected with ACS at HST and together with WFC3 (UVIS, IR) allowed us to mea…
