Title: Exploring the Physical Properties of Planetary Nebula NGC 3132 with MUSE, JWST and SPITZER data.
Abstract:

Imaging spectroscopy, also known as integral field spectroscopy, is a valuable tool for analyzing extended ionized nebulae like planetary nebulae (PNe), H II regions, galaxies. PNe are the remnants of low to intermediate-mass stars (1-8 M_⊙) that have expelled their outer layers. In this study, a two-dimensional spectroscopic analysis has been performed on the PN NGC 3132 using data from the MUSE. NGC 3132 was chosen for the early observing phase of the JWST, and multiple stellar system were discovered as well as significant molecular hydrogen emissions. Additionally, archival data from the Spitzer telescope were combined with JWST images to examine the radial distribution of near-infrared emission line ratios and IRAC colors. The average electron temperature of NGC 3132 was found close to, 9500 K, while the electron density ranges from 500 to 900 cm^-3. Chemical composition variations in this nebular gas are ruled out. The radial analysis of optical and infrared lines shows a strong correlation between the c(Hβ) and emission lines, indicating the presence of significant amounts of dust that prevent molecular hydrogen dissociation. The physical and chemical properties of the nebula are mapped and compared to the predictions of a 3D photoionization model in order to constrain its physical characteristics.
