Near-Infrared Observations of RR Lyrae Variables in Centauri
M. Del Principe, A. M. Piersimoni, J. Storm +6
We present Near-Infrared (NIR) and -band observations for 181 RR Lyrae stars in the Galactic Globular Cluster Cen. The comparison between predicted and empirical slope…
The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
Near-Infrared photometry of LMC cluster Reticulum
M. Dall'Ora, G. Bono, J. Storm +11
We present near-infrared (JKs) time series data of the Large Magellanic Cloud (LMC) cluster Reticulum. The observing strategy and data reduction (DAOPHOTII/ALLFRAME) allowed us to…
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…
Star luminosity function as an age indicator for the Dwarf spheroidal Leo I
F. Caputo, V. Castellani, S. Degl'Innocenti
Star luminosity function, already recognized as an age indicator for old galactic globular clusters, can be used to contrains the age of younger stellar systems like the nearby dwa…
