TL;DR
This paper estimates distances to two planetary nebulae, Abell 39 and NGC 7027, using 3-D photoionization models, providing preliminary measurements with about 30% uncertainty.
Contribution
It introduces a method of using 3-D photoionization modeling to estimate distances to planetary nebulae.
Findings
Estimated distances: 1.5 kpc for Abell 39 and 0.9 kpc for NGC 7027.
Uncertainties in distance estimates are approximately 30%.
Demonstrates the application of the MOCASSIN code for distance estimation.
Abstract
We estimate distances to the spherical planetary nebula Abell 39 and the bipolar planetary nebula NGC 7027 by interpolating from a wide grid of photoionization models using the 3-D code, MOCASSIN. We find preliminary distances of 1.5 kpc and 0.9 kpc respectively, with uncertainties of about 30%.
