Variable stars in Stellar Systems
Giuseppe Bono, Silvia Petroni, Marcella Marconi
We discuss in detail the pulsation properties of variable stars in globular clusters (GCs) and in Local Group (LG) dwarf galaxies. Data available in the literature strongly support…
Mass-to-light ratios in early-type galaxies and the dark matter content
M. Capaccioli, N. R. Napolitano, M. Arnaboldi
The distribution of the radial trends of the mass-to-light ratios (M/L) within an assorted sample of early-type galaxies is discussed. Three classes of galaxies are identified acco…
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…
Surface Brightness Fluctuations: a theoretical point of view
M. Cantiello, G. Raimondo, E. Brocato +1
We present new theoretical evaluations of optical and near-IR Surface Brightness Fluctuations (SBF) magnitudes for single-burst stellar populations in the age range t=5-15 Gyr and…
