Blanketing sporadic E layer near the magnetic equator

Chandra, H; Rastogi, R. G (American Geophysical Union, 1975-01)

A study of the ionograms obtained at Kodaikanal (dip latitude 1.7 N) during the period 1954-1966 has shown that the daily variation of the occurrence of the blanketing type of sporadic E has a major peak around 1700 LT in ...
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 ...
A dependence on solar cycle of the size of the Ca/+/ network

Singh, J; Bappu, M. K. V (Springer, 1981-05)

Calcium network diameters are shown to be smaller by 5% at solar maximum than at minimum. The average cell size at minimum is 22,115 + or - 99 km. The average size at solar maximum is 20,920 + or - 112 km, though individual ...
Emission lines from nitrogen-like ions and their diagnostic use

Raju, P. K; Dwivedi, B. N (Kluwer Academic Publishers, 1990-11)

Line emissions from nitrogen-like ions NeIV, MgVI, and AlVII have been studied as a diagnostic probe for the emitting regions of astrophysical plasma. Line intensities from these ions have been calculated and compared, in ...
