Radiation transfer in the cavity and shell of a planetary nebula.

GRAY M.D., MATSUURA M. and ZIJLSTRA A.A.

Abstract (from CDS):

We develop an approximate analytical solution for the transfer of line-averaged radiation in the hydrogen recombination lines for the ionized cavity and molecular shell of a spherically symmetric planetary nebula. The scattering problem is treated as a perturbation, using a mean intensity derived from a scattering-free solution. The analytical function was fitted to Hα and Hβ data from the planetary nebula NGC 6537. The position of the maximum in the intensity profile produced consistent values for the radius of the cavity as a fraction of the radius of the dusty nebula: 0.21 for Hα and 0.20 for Hβ. Recovered optical depths were broadly consistent with observed optical extinction in the nebula, but the range of fit parameters in this case is evidence for a clumpy distribution of dust.
