Modelagem de nebulosas planetárias com morfologia bipolar
Keywords in Portuguese

fotoionização
nebulosa planetária
Abstract in Portuguese
O presente trabalho propõe-se a mapear espacialmente as propriedades físicas de um conjunto destes objetos, de morfologia bipolar, e então efetuar sua modelagem. Para este mapeamento foram executadas observações do Observatório Pico dos Dias (LNA/MCT) através das técnicas observacionais de espectroscopia de fenda longa e de campo integral. As modelagens foram executadas com o código de fotoionização CLOUDY em seu formato pseudo tridimensional, CLOUDY_3D. Nossos resultados mostram que as simulações são capazes de reproduzir em boa medida o quadro de observações realizadas, mesmo partindo de considerações simplificadoras para a construção do ambiente astrofísico analisado. Como produto, estabelece-se limites para os parâmetros dos objetos, tais como características da distribuição de matéria, propriedades da fonte central, distância e dimensões envolvidas.

Abstract in English
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.
