Abstract
We carried out near- to mid-infrared imaging and spectroscopic observations of patchy areas in the Small Magellanic Cloud using the Infrared Camera aboard AKARI. Two 100 arcmin² areas were imaged in 3.2, 4.1, 7, 11, 15, and 24μm, and also spectroscopically observed in the wavelength range continuously from 2.5 to 13.4μm. The spectral resolving power, λ/Δλ, values were about 20, 50, and 50 at 3.5, 6.6, and 10.6μm, respectively. Other than the two 100 arcmin² areas, some patchy areas were imaged and/or spectroscopically observed as well. In this paper, we overview the observations and present a list of near- to mid-infrared photometric results, which lists ∼12000 near-infrared and ∼1800 mid-infrared bright point sources detected in the observed areas. The 10σ limits are 16.50, 16.12, 13.28, 11.26, 9.62, and 8.76 in Vega magnitudes at 3.2, 4.1, 7, 11, 15, and 24μm bands, respectively.
