The Updated BaSTI Stellar Evolution Models and Isochrones: I. Solar
  Scaled Calculations
  We present an updated release of the BaSTI (a Bag of Stellar Tracks and
Isochrones) stellar model and isochrone library for a solar scaled heavy
element distribution. The main input physics changed from the previous BaSTI
release include the solar metal mixture, electron conduction opacities, a few
nuclear reaction rates, bolometric corrections, and the treatment of the
overshooting efficiency for shrinking convective cores. The new model
calculations cover a mass range between 0.1 and 15 Msun, 22 initial chemical
compositions between [Fe/H]=-3.20 and +0.45, with helium to metal enrichment
ratio dY /dZ=1.31. The isochrones cover an age range between 20 Myr and 14.5
Gyr, take consistently into account the pre-main sequence phase, and have been
translated to a large number of popular photometric systems. Asteroseismic
properties of the theoretical models have also been calculated. We compare our
isochrones with results from independent databases and with several sets of
observations, to test the accuracy of the calculations. All stellar evolution
tracks, asteroseismic properties and isochrones are made available through a
dedicated Web site.
