AKARI/IRC Near-Infrared Spectral Atlas of Galactic Planetary Nebulae

Abstract

Near-infrared (2.5-5.0$\mu$m) low-resolution ($\lambda /\Delta \lambda \sim 100$) spectra of 72 Galactic planetary nebulae (PNe) were obtained with the Infrared Camera (IRC) in the post-helium phase. The IRC, equipped with a $1^{\prime }\times 1^{\prime }$ window for spectroscopy of a point source, was capable of obtaining near-infrared spectra in a slit-less mode without any flux loss due to a slit. The spectra show emission features including hydrogen recombination lines and the 3.3-3.5$\mu$m hydrocarbon features. The intensity and equivalent width of the emission features were measured by spectral fitting. We made a catalog providing unique information on the investigation of the near-infrared emission of PNe. In this paper, details of the observations and characteristics of the catalog are described.
