The coronal line regions of planetary nebulae NGC 6302 and 6537: 3-13 mu m grating and echelle spectroscopy

Abstract:

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 CLOUDY), which allow us to re-estimate the temperature of the central star to be about 250 000 K. All of the detected lines are consistent with this value, except for [Al V] and [Al VI]. Aluminium i...
