Emissivity line ratios for [Mn III] and spectral diagnostics of H II regions
Zher Samak, Sultana N. Nahar, Anil K. Pradhan
We present the first theoretical emission-line study of Mn III as potential determinant of physical conditions and manganese abundance. We compute atomic data for a set of Mn III l…

The Opacity Project: R-Matrix Calculations for Opacities of High-Energy-Density Astrophysical and Laboratory Plasmas
Anil K. Pradhan, Sultana N. Nahar
Accurate determination of opacity is critical for understanding radiation transport in both astrophysical and laboratory plasmas. We employ atomic data from R-Matrix calculations t…
