a) False-color composite image of SMCB2-H ii from Spitzer IRAC bands 3.6 μm (blue), 4.5 μm (green), and 8 μm (red). The various H ii regions detected by Henize (1956) in this part of the SMC are labeled, as well as the YSO candidates (Sect. 4.6). The image center is α = 0^h48^m0185, δ = −73°16′03.̋75. Total field size 168′′ × 251′′ or 50 × 76 pc. b) The MIPS 24 μm image of the SMCB2-HII region with the CO contours overlaid. The contours outline the molecular cloud SMCB2 (Bot et al. 2010). The bright stars are labeled (see electronic edition of the journal for a color version of this figure).
