Line-radiation transfer - Comparative approximations
Abstract
Some highly accurate approximate solutions to the radiative transfer problem for spectral lines, which before long may radically change the way that line-radiation fields are calculated in non-LTE atmospheres, are compared against the exact asymptotic solutions given by analytic methods. Standard line-formation theory serves as a working example.
