Optical image of IC 10, with I, B, and V band images as RGB colors. The outer circles (7″ radius; ≈24 pc) are centered on the point-like sources with silicate emission (Table 1). The inner circles (4″ radius; ≈14 pc) indicate the position of the 2MASS counterpart (Table 2). The size of the circles is chosen just for display purposes. The IRS spectra are extracted from a beam with FWHM ≈ 4″.
