Abstract

Absorption and scattering of sunlight in a calcium plasma cloud at λ0 = 397 nm under the conditions of pulsating mass dynamics is analyzed. The problem is described by a set of integrodifferential equations and is solved numerically for the case of 3D spherical geometry of emitting plasma and harmonic variation of the expansion velocity of the plasma sphere. The causes of the frequency asymmetry of the spectral line contour for the emission scattered by the cloud along different ray directions ate analyzed.
