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…
Galactic Globular Clusters Database: a progress report
M. Castellani
The present status of Galactic Globular Clusters Database is briefly reviewed. The features implemented at the time writing are described, as well as plans for future improvements.
Multiwavelength Time Series Data of the LMC Cluster Reticulum
M. Monelli, G. Andreuzzi, G. Bono +11
We present accurate multiwavelength UBVI time series data of the LMC cluster Reticulum. Data cover a time interval of ~ 6 yr and have been collected with SUSI1/2 and SOFI at NTT/ES…
Antlia: an outskirt Local Group Galaxy
Marco Castellani, Giuseppe Bono, Santi Cassisi +2
Deep (I,V-I) and (I,B-I) color-magnitude diagrams (CMDs) of the Antlia dwarf galaxy, based on Science Verification (SV) data collected with the FORS I camera on the ESO Very Large…
A new investigation on the Antlia Dwarf Galaxy
A. M. Piersimoni, G. Bono, M. Castellani +4
We present deep (I,V-I) and (I,B-I) color-magnitude diagrams (CMDs) of the Antlia dwarf galaxy, based on Science Verification (SV) data collected with the FORS I camera on the ESO…
HST Photometry of the Fornax dSph Galaxy: cluster 4 and its field
R. Buonanno, C. E. Corsi, M. Castellani +3
Using observations from the Hubble Space Telescope archive, color-magnitude diagrams (CMDs) have been constructed for globular cluster 4 in the Fornax dSph galaxy and its surroundi…
