Abstract

A group of stars embedded in an emission nebula near the cluster NGC 7822 has been discovered to have a unique interstellar spectrum, characterized by exceedingly strong CN lines. Evidence is presented favoring the hypothesis that the CN molecules arise in the immediate neighborhood of the H 11 region boundary. It is further suggested that the CN molecules are formed in the solid particles of the Hr region when flashed by the UV radiation in the advancing ionization front.
