On the radial extent of the dwarf irregular galaxy IC10
N. Sanna, G. Bono, P. B. Stetson +16
We present new deep and accurate space (Advanced Camera for Surveys -- Wide Field Planetary Camera 2 at the Hubble Space Telescope) and ground-based (Suprime-Cam at Subaru Telescop…
On the absolute age of the Globular Cluster M92
A. Di Cecco, R. Becucci, G. Bono +15
We present precise and deep optical photometry of the globular M92. Data were collected in three different photometric systems: Sloan Digital Sky Survey (g',r',i',z'; MegaCam@CFHT)…
Insights into the Cepheid distance scale
G. Bono, F. Caputo, M. Marconi +1
We present an investigation of Cepheid distances using theory and observations. Cepheid models indicate that the slope of the Period-Luminosity (P-L) relation covering the entire p…
New Baade-Wesselink distances and radii for four metal-rich Galactic Cepheids
S. Pedicelli, B. Lemasle, M. Groenewegen +10
We provided accurate estimates of distances, radii and iron abundances for four metal-rich Cepheids, namely V340 Ara, UZ Sct, AV Sgr and VY Sgr. The main aim of this investigation…
On the Delta V_HB_bump parameter in Globular Clusters
A. Di Cecco, G. Bono, P. B. Stetson +21
We present new empirical estimates of the Delta V_HB_bump parameter for 15 Galactic globular clusters (GGCs) using accurate and homogeneous ground-based optical data. Together with…
