Deconstructing IRAS 07027-7934.

SURENDIRANATH R.

Abstract (from CDS):

The planetary nebula IRAS 07027-7934 has a compact ionized core surrounded by a large cloud of matter believed to be of neutral gas and dust particles. A photoionization model of this ionized core is presented in this paper. The parameters Teff, R*, and distance of the central star along with the radius of the nebula are derived by photoionization modeling. The nebula is found to have a much lower electron temperature than was estimated earlier but the electron density is very high, in broad agreement with previous result. The abundances derived for the first time point to a C/O ratio of >5 for the nebula, and the internal extinction caused by the ionized core, E(B-V), is 2.
