论文摘要
这是专门介绍Basti（一袋Stellar Tracks and Isochrones）恒星模型和等距库的更新版本的系列文章。在发布更新的太阳能缩放库后，我们在这里向图书馆介绍了$α-$增强的重元分布。这些新的α增强模型可以说明参考太阳金属分布和物理输入中的所有改进和更新，如新的太阳能缩放库中。这些模型覆盖质量范围在0.1至$ 15〜m _ {\ odot} $，[fe/h] = -3.20和+0.06之间的18个金属度，[alpha/fe] = +0.4，以及氦与金属富集比delta {y}δ{y}δ{z} = 1.31。对于每种金属性，还提供了具有恒星模型。等速线覆盖（通常）在20myr和14.5Gyr之间的年龄范围，包括始终如一的序列阶段。还已经计算出理论模型的小星言特性。已将模型和同句与独立计算的结果，先前的Basti释放以及选定的观测值进行了比较，以测试这些新计算的准确性/可靠性。所有恒星进化轨道，星空症的特性和等距均可在http://basti-iac.oa-teramo.inaf.it上公开获得。
This is the second paper of a series devoted to present an updated release of the BaSTI ( a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the publication of the updated solar scaled library, here we present the library for a $α-$enhanced heavy element distribution. These new alpha-enhanced models account for all improvements and updates in the reference solar metal distribution and physics inputs, as in the new solar scaled library. The models cover a mass range between 0.1 and $15~M_{\odot}$, 18 metallicities between [Fe/H]=-3.20 and +0.06 with [alpha/Fe]=+0.4 , and a helium to metal enrichment ratio Delta{Y}Δ{Z}=1.31. For each metallicity, He-enhanced stellar models are also provided. The isochrones cover (typically) an age range between 20Myr and 14.5Gyr, including consistently the pre-main sequence phase. Asteroseismic properties of the theoretical models have also been calculated. Models and isochrones have been compared with results from independent calculations, with the previous BaSTI release, and also with selected observations, to test the accuracy/reliability of these new calculations. All stellar evolution tracks, asteroseismic properties and isochrones are made publicly available at http://basti-iac.oa-teramo.inaf.it
