非麦克斯韦电子卡帕分布的H到Zn电离平衡:更新的计算

H to Zn Ionization Equilibrium for the Non-Maxwellian Electron kappa-distributions: Updated Calculations

Elena Dzifcakova, Jaroslav Dudik

摘要:

在过去的几年中,已经公布了用于计算电离和复合速率的新数据。其中大部分已纳入CHIANTI数据库。我们用这些数据来计算碰撞电离和复合率的非麦克斯韦卡帕分布的粒子数增加的高能量的尾巴,这已被发现在太阳过渡区和太阳风。导出了元素H ~ Zn的电离平衡。κ分布显著影响电离和复合速率,并加宽离子丰度峰。与麦克斯韦分布相比,离子丰度峰也可以向更低或更高的温度移动。更新的电离平衡计算结果在几个离子,特别是Fe八-十四大的变化。结果以与CHIANTI数据库兼容的电子形式提供。

英文摘要:

New data for calculation of the ionization and recombination rates have have been published in the past few years. Most of these are included in CHIANTI database. We used these data to calculate collisional ionization and recombination rates for the non-Maxwellian kappa-distributions with an enhanced number of particles in the high-energy tail, which have been detected in the solar transition region and the solar wind. Ionization equilibria for elements H to Zn are derived. The kappa-distributions significantly influence both the ionization and recombination rates and widen the ion abundance peaks. In comparison with Maxwellian distribution, the ion abundance peaks can also be shifted to lower or higher temperatures. The updated ionization equilibrium calculations result in large changes for several ions, notably Fe VIII--XIV. The results are supplied in electronic form compatible with the CHIANTI database.
