The near-IR luminosity-metallicity relationship for dwarf irregular galaxies
Ivo Saviane, R. Riegerbauer, E. V. Held +6
We briefly describe our on-going investigation of the near-IR luminosity-metallicity relationship for dwarf irregular galaxies in nearby groups of galaxies. The motivations of the…

The relative ages of LMC old clusters, and the case of NGC 1841
Ivo Saviane, Alfred Rosenberg, Giampaolo Piotto +1
Using archival HST/WFPC2 imaging of 7 LMC globular clusters, and following the methods outlined in our previous study, we have reached the tightest constrain so far on their age di…

Does the mixing length parameter depend on metallicity?
Rossella Palmieri, Giampaolo Piotto, Ivo Saviane +2
This paper is a further step in the investigation of the morphology of the color-magnitude diagram of Galactic globular clusters, and the fine-tuning of theoretical models, made po…
