The relative distribution of ammonia and cyanobutadiyne emission in Heiles 2 dust cloud
- 1. Observatoire de Paris, Section de Meudon, 92 (France)
Description
A map of the NH3 (1,1) emission in Heiles 2 dust cloud, observed with 2.2 arcmin resolution, is presented and compared with that of the J = 9 → 8 transition of HC5N. Although the distribution of the emission of both molecules lies on a ridge, there is a marked anticorrelation in the observed antenna temperatures of the two molecules along it. This appears to be best explained as a variation in the relative abundances of the two molecules along the ridge by a factor of 8 to 20 in a distance of 1018 cm. (author)
