Atomic data from the Iron Project.LVIII. New radiative transition probabilities for Fe IV including fine structure
Sultana N. Nahar, Anil K. Pradhan
We present new calculations for transition probabilities of Fe IV, with much more extensive datasets than heretofore available. The large-scale close coupling R-matrix calculations…
Theoretical FeI/II/III Emission-Line Strengths from Active Galactic Nuclei with Broad-Line Regions
T. A. A. Sigut, Anil K. Pradhan, Sultana N. Nahar
We present theoretical iron emission line strengths for physical conditions typical of Active Galactic Nuclei with Broad-Line Regions. The non-local thermodynamic equilibrium (NLTE…
Atomic data from the Iron Project. LIII. Relativistic allowed and forbidden transition probabilities for Fe XVII
Sultana N. Nahar, Werner Eissner, Guo-Xin Chen +1
An extensive set of fine structure levels and corresponding transition probabilities for allowed and forbidden transitions in Fe XVII is presented. A total of 490 bound energy leve…
The Iron Project and Non-LTE stellar modeling
Sultana N. Nahar
Latest developments in theoretical computations since the international Opacity Project (OP), under the new the Iron Project (IP) and extensions, are described for applications to…
Atomic Processes in Planetary Nebulae
Sultana N. Nahar
A hot central star illuminating the surrounding ionized H II region usually produces very rich atomic spectra resulting from basic atomic processes: photoionization, electron-ion r…
