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…
The stellar content of the Sagittarius Dwarf Galaxy
G. Marconi, R. Buonanno, M. Castellani +4
We present V,I deep CCD photometry for three fields of the dwarf galaxy in Sagittarius (Sgr). One of the fields is centered on the globular cluster NGC 6715 (M54), which lies in on…
"Not too old" metal deficient stellar populations: the case of metallicity Z=0.00001
S. Cassisi, M. Castellani, V. Castellani
We investigate the evolution of metal deficient stellar structures, presenting H-burning isochrones covering cluster ages from 800 Myr to 7 Gyr. Evolutionary evidences for selectio…
