Discretization of the equation of Radiative Transfer with Compton Scattering

Peraiah, A (Indian Institute of Astrophysics, Bangalore, 1986-05)

We have attempted to solve the equation of radiative transfer by including Compton and inverse Compton scattering. We expanded the specific intensity by Taylor series at about v/sup1/ = v/sub0/. The resulting equation has ...
Effects of Velocities on Ca II H and K Lines

Rangarajan, K. E; Mohan Rao, D; Peraiah, A (Indian Institute of Astrophysics, Bangalore, 1981)

Ca II H and K (3968, 3933) and infrared triplet lines lamda lamda lamda 8498, 8662, 8542 were calculated in a very slowly expanding medium. Five level atom with continuum was considered. Radiative transfer equation and ...
P Cygni type profiles

Peraiah, A; Srinivasa Rao, M (Indian Institute of Astrophysics, Bangalore, 1985-11)

We have presented a series of P Cygni type profiles of special lines computed by employing different velocity laws of expansion in a spherically atmosphere. A comparison has been made with those of Beals classification. ...
Simultaneous Solution of Radiative Transfer Equation in the Comoving Frame and the Statistical Equilibrium Equation with Complete Redisribution

Peraiah, A (Indian Institute of Astrophysics, Bangalore, 1980)

Complete redistribution with Voigt profile function has been employed in obtaining the simultaneous solution of line transfer and the statistical equilibrium equation for a non-LTE two level atom in an extended stellar ...
