G. Hunerth et P. Ulmschneider, LINE RADIATION COOLING WITH PARTIAL REDISTRIBUTION IN ATMOSPHERES WITH SHOCKS, Astronomy and astrophysics, 293(1), 1995, pp. 166-171
We investigate the energy loss by spectral line radiation assuming par
tial redistribution PRD in atmospheres permeated by acoustic shock wav
es. It is found that with PRD the emission is much reduced and much mo
re concentrated in a narrow region behind the shocks compared to cases
which assume complete redistribution CRD. A fast method to approximat
e the radiation losses for time-dependent calculations is proposed.
