Molecular hydrogen emission from the Cepheus A star-formation region

  • 1. Observatoire du Mont Megantic, Montreal (Canada)

Description

Fabry-Perot spectrometry of H2 emission lines in the Cepheus A star-formation region is presented. It is found that the H2 emission in Cep A(E) is associated with dense condensations of NH3 and CS, while the emission in Cep A(W) is associated with Herbig-Haro objects and reflection nebulae. The data support the hypothesis that the two lobes of emission are produced by a single outflow originating from the region of maser and compact H II regions at the western edge of Cep A(E). 49 references
