Abstract
Observations of the spectrum of G333.6–0.2 between 8 µ and 13 µ show emission from the Ne II line at 12.80 µ , A neon abundance in the range 7.63–7.93 is found, in agreement with recent estimates of the cosmic abundance of neon. The continuum radiation is considered to be thermal emission from optically thin dust with extinction in a thicker cold dust envelope, both distributions containing silicates, and the optical depth of the dust in emission is consistent with the observed ratio infrared/Ly α excess.Keywords
