For pt.I, see ibid., vol.20, no.1, p.163-78 (1987). This paper is the second of a series investigating time-dependent radiative transfer processes of X-rays in photospheric plasmas. The authors present a quantitative discussion of analytical results derived earlier and a comparison with Monte Carlo simulations. The geometry considered is a homogeneous plasma ball with radius R. The source is concentrated on a concentric shell with radius r<sub>0</sub>(R. Point sources at the centre of the ball or semi-infinite geometries are discussed as limiting cases. The time profile for the source can be arbitrary. Diffusion profiles are given for every scattering order and the total profile appears as the sum over these individual profiles. The comparison with Monte Carlo results is used to test the accuracy of the analytical approach and to adjust the time profiles of the first few scattering orders. The analytical theory yields good results over a wide range of situations with remarkable numerical efficiency. All results can be calculated on a microcomputer. |
