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 ~ { } M _ { \odot } , 22 initial chemical compositions between [ Fe/H ] = - 3.20 and + 0.45 , with helium to metal enrichment ratio d Y /d Z =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 .
