我们提供了Chianti软件包的第10版。在这个版本中，我们提供了几个类氦离子和所有的铍，碳，镁等电子序列的离子，是丰富的天体物理等离子体更新的原子模型。我们包括从大规模的原子结构和散射计算，在许多情况下是一个显着的改进，比以前的版本，特别是Be样序列，它有有用的线诊断测量的电子密度和温度的速率。我们还添加了新的离子，并更新了其中几个新的原子速率和线标识。此外，我们还对IDL软件进行了一些改进，以加快计算速度并估计双电子复合的抑制。
We present version 10 of the CHIANTI package. In this release, we provide updated atomic models for several helium-like ions and for all the ions of the beryllium, carbon, and magnesium isoelectronic sequences that are abundant in astrophysical plasmas. We include rates from large-scale atomic structure and scattering calculations that are in many cases a significant improvement over the previous version, especially for the Be-like sequence, which has useful line diagnostics to measure the electron density and temperature. We have also added new ions and updated several of them with new atomic rates and line identifications. Also, we have added several improvements to the IDL software, to speed up the calculations and to estimate the suppression of dielectronic recombination.
