We present spatially resolved mid-infrared spectroscopy of the Class I/flat-spectrum protostellar binary system SVS 20 in the Serpens cloud core. The spectra were obtained with the mid-infrared instrument T-ReCS on Gemini South. SVS 20-South, the more luminous of the two sources, exhibits a mid-infrared emission spectrum peaking near 11.3 μm, while SVS 20-North exhibits a shallow amorphous silicate absorption spectrum with a peak optical depth of τ ~ 0.3. After removal of the line-of-sight… Expand
