cds-question@unistra.fratomic-physicsNew calculations of the energy levels, radiative transition rates, and collisional excitation rates of Fe IX have been carried out using the Flexible Atomic Code (FAC; Gu 2003ApJ...582.1241G), 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 Solar Dynamics Observatory Atmospheric Imaging Assembly (SDO/AIA) observations using the 94{AA} filter.2011ApJ...740L..52Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/740/L52CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/164/297 : New relativistic atomic data for Fe IX (Verma+, 2006)J/A+A/460/331 : Fe IX radiative and excitation rates (Aggarwal+, 2006)J/A+A/410/359 : Radiative and Auger decay for Fe II-Fe IX (Palmeri+, 2003)J/A+A/394/753 : IRON Project.
