Studies of NGC 6720 with Calibrated \u3cem\u3eHST\u3c/em\u3e/WFC3 Emission-line Filter Images. I. Structure and Evolution

, 2013
We have performed a detailed analysis of the Ring Nebula (NGC 6720) using Hubble Space Telescope WFC3 images and derived a new three-dimensional model. Existing high spectral resolution spectra played an important supplementary role in our modeling.
