The coronal line regions of planetary nebulae NGC 6302 and 6537: 3-13 mu m grating and echelle spectroscopy
We report on advances in the study of the cores of NGC 6302 and 6537 using infrared grating and echelle spectroscopy. In NGC 6302, emission lines from species spanning a large range of ionization potential, and in particular [Si IX] 3.934 μm, are interpreted using photoionization models (including C...
