Theory of multiple-stellar population synthesis in a non-Hamiltonian setting
S. Pasetto, D. Crnojević, G. Busso +2
We aim to investigate the connections existing between the density profiles of the stellar populations used to define a gravitationally bound stellar system and their star formatio…
Enhancement of alpha-Elements in Dynamical Models of Elliptical Galaxies
R. Tantalo, C. Chiosi
In this paper we present a quantitative analysis of the chemical abundances in "monolithic" N-body-Tree-SPH models of elliptical galaxies to determine whether the ratio [alpha/Fe]…
NGC 1866: a workbench for stellar evolution
Roberto Barmina, Leo Girardi, Cesare Chiosi
The young LMC cluster NGC 1866 represents the ideal laboratory for testing stellar evolutionary models: in particular, it can be used to discriminate among classical stellar models…
Evolutionary tracks and isochrones for alpha-enhanced stars
Bernardo Salasnich, Leo Girardi, Achim Weiss +1
We present four large sets of evolutionary tracks for stars with initial chemical compositions [Y=0.250, Z=0.008], [Y=0.273, Z=0.019], [Y=0.320, Z=0.040] and [Y=0.390, Z=0.070] and…
Is the galactic disk older than the halo?
Giovanni Carraro, Leo Girardi, Cesare Chiosi
Aim of this study is to infer the age of the Galactic Disk by means of the ages of old open clusters, and comment on some recent claims that the Galactic Disk can be older than the…
HST observations of the Local Group dwarf galaxy Leo I
C. Gallart, W. L. Freedman, M. Mateo +10
We present deep HST F555W (V) and F814W (I) observations of a central field in the Local Group dwarf spheroidal (dSph) galaxy Leo I. The resulting color-magnitude diagram (CMD) rea…
