Abstract

This study aims to map spatially the physical properties of a set of objects, with bipolar morphology, and then build their models. For this mapping, observations were performed at the Pico dos Dias Observatory (LNA / MCT) using the observational techniques of long slit and integral field spectroscopy. Modeling was performed with the photoionization code CLOUDY in its pseudo three-dimensional format, CLOUDY_3D. Our results show that the simulations are able to reproduce the major features of observations, even taking simplifying assumptions for the astrophysical environment analyzed. As a product, it establishes limits for the parameters of objects, such as characteristics for the distribution of matter, properties of the central star, distances and related dimensions. (AU)
