We present N-band (8–13 μm) spectroscopic observations of the low-mass, embedded pre-main-sequence close binary system SVS13. Absorption features are clearly detected which are attributable to amorphous silicates, crystalline forsterite, crystalline enstatite and annealed SiO2. Most intriguingly, a major component of the dust in the envelope or disc around SVS13 appears to be SiC, required to mode...
