太阳动力学观测的Fe IX计算

Fe IX Calculations for the Solar Dynamics Observatory

Adam R Foster, Paola Testa

摘要:

新的计算的能级,辐射跃迁率和碰撞激发率的\ion{Fe}{ix}已进行使用灵活的原子代码,密切关注实验确定的水平和扩展现有的计算到更高的能级。对于较低的水平,R-矩阵碰撞激发率从早期的工作已被使用。通过这些计算预测了5 f-3d跃迁中的显著发射,这将影响使用94 μ m滤波器对SDO AIA观测的分析。

英文摘要:

New calculations of the energy levels, radiative transition rates and collisional excitation rates of \ion{Fe}{ix} have been carried out using the Flexible Atomic Code, paying close attention to experimentally identified levels and extending existing calculations to higher energy levels. For lower levels, R-matrix collisional excitation rates from earlier work have been used. Significant emission is predicted by these calculations in the 5f-3d transitions, which will impact analysis of SDO AIA observations using the 94Å filter.
