Density dependence of the line source functions in scattering media

Peraiah, A (D. Reidel Publishing Co., 1983-09)

The author has calculated source functions in a scattering medium in which the density changes according to the law of Ne(r) ≡ rn where n takes the value from -3 to +3 and Ne(r) is the electron density. He has assumed that ...
Discrete space theory of radiative transfer

Peraiah, A (Cambridge University Press, 1984)

A discrete space theory for radiative transfer based on invariant imbedding is described, along with applications. An interaction principle is defined for the relation between incident and emitted radiation from an optically ...
Energy transport in intense flux tubes on the sun. I - Equilibrium atmosphere

Hasan, S. S (The American Astronomical Society, 1988-09)

Model calculations are performed to determine self-consistently the equilibrium atmosphere in an intense flux tube. The generalization of the Eddington approximation to three dimensions is used to develop a zeroth-order ...
Line formation in spherical media with partial frequency redistribution. I - Solution of the line transfer

Peraiah, A (Kluwer Academic Publishers, 1978-09)

The solution of line transfer with partial redistribution for an arbitrary (i.e., either stationary or moving) spherical medium is formulated in the framework of discrete space theory. The equation of line transfer for a ...
Observations of the continuum radio emission from the undisturbed Sun at a wavelength of 8.7 meters

Sastry, Ch. V (Springer, 1994-03)

We have mapped the continuum emission from the undisturbed Sun at a wavelength of 8.7 m during 1981-1985 using the large decameter-wave radio telescope at Gauribidanur, India with a resolution of 26 x 38 arc min. During ...
The radio brightness of the undisturbed outer solar corona in the presence of a radial magnetic field

Golap, K; Sastry, Ch. V (Springer, 1994-03)

The radio brightness of the quiet outer solar corona at a frequency of 35 MHz in the presence of a radial magnetic field is computed. It is found that the brightness temperature of the ordinary radiation increases ...
