Description
The authors present an improved iterative method for deriving
temperature corrections in stellar atmospheres. At each step of
iteration, the procedure computes, from the current values of the
radiation field, a set of depth-dependent factors, averaged over angles
and frequencies. Even a crude initial estimate of the radiation field
leads to a fairly accurate determination of these factors on the first
iteration: they are quasi-invariant in subsequent iterations. For a
range of effective temperatures the procedure quickly converges to the
correct solution of the radiative transfer equation. At each iteration,
the temperature distribution is directly derived via the energy
conservation constraint.
