Scientific paper

We present a 0.9-2.5 μm spectrum of V445 Puppis obtained about 3 years after maximum brightness. The spectrum shows thermal continuum emission and two narrow, structured emission lines: He I 1.0830 μm and 2.0581 μm. We interpret this to be emission from a hydrogen-deficient, helium-rich, low-temperature nebula surrounded by an optically thick dust shell, probably carbonaceous.
