Infra-Red Observations of Young Stars-III: NEBULOUS EMISSION-LINE STARS

Abstract

Multifilter infra-red observations of early-type nebulous stars are presented in the 2 to 22 µ region. Emission features in the 10 µ region are found in the stars AB Aur and V380 Ori. It is found that stars associated with cometary nebulae are characterized by large [11]–[18] indices and this is discussed in the context of a possible picture of these nebulae.
