Star counts in the Galaxy. Simulating from very deep to very shallow photometric surveys with the TRILEGAL code
L. Girardi, M. A. T. Groenewegen, E. Hatziminaoglou +1
We describe TRILEGAL, a new populations synthesis code for simulating the stellar photometry of any Galaxy field. The code attempts to improve upon several technical aspects of sta…
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…
Near-infrared photometry of the young open clusters NGC 1893 and Berkeley 86
Antonella Vallenari, Andrea Richichi, Giovanni Carraro +1
We present photometry in the J and K near-infrared bands for two regions centered on the young open clusters NGC 1893 and Berkeley 86. We study 700 stars down to K = 17 in the fiel…
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…
