Combined modelling of the He-131 planetary nebula and its central star.
Abstract
We present the preliminary results of an auto-consistent
model of He 2-131 planetary nebula and its central star. We model
the star using the CMFGEN code and then we use its spectral energy distribution as input
to the CLOUDY-3D photoionization code to compute the intensities of the nebular emission lines and their profiles. We iterate between the two codes
until we are able to reproduce the charecteristics of stellar spectrum and of the nebular lines.
One of the important outcomes of our study is the comparison of the chemical composition of the stallar atmosphere and that of the nebula.
