The Galactic globular cluster NGC 1851: its dynamical and evolutionary properties
I. Saviane, G. Piotto, F. Fagotto +3
We have completely mapped the globular cluster NGC 1851 with VI CCD photometry, obtaining a CMD for ca. 20500 stars. From the apparent luminosity of the HB we derive a distance mod…

Spectro-photometric Evolution of Elliptical Galaxies. II. Models with infall
R. Tantalo, C. Chiosi, A. Bressan +1
In this paper we present new chemo-spectro-photometric models of elliptical galaxies in which infall of primordial gas is allowed to occur. They aim to simulate the collapse of a g…
