Density and temperature diagnostics of solar emission lines from NA VII and AL IX

Raju, P. K; Dwivedi, B. N; Gupta, A. K (Springer, 1994-02)

Line intensity ratios of extreme ultraviolet (EUV) emission lines from Na VII and Al IX have been considered for electron density and temperature determinations within the chromosphere-corona transition region and the ...
Density dependence of solar emission lines of boron-like ions

Dwivedi, B. N; Raju, P. K (Kluwer Academic Publishers, 1980-11)

Steady state level densities of 20 levels of the boron-like ions Mg VII and Si X have been computed as a function of electron density and temperature. Collisional and spontaneous radiative processes have been accounted ...
On the EUV Line Diagnostics From N III Solar Ion

Gupta, A. K; Mohan, A; Dwivedi, B. N (Astronomical Society of India, 1997)

We present new calculations for N III ion for diagnostics of solar plasma. The atomic model comprising the first 15 energy levels is considered for evaluating the line emissivities as a function of electron density and ...
