31 Aug 2003 | Journal: | Astron.Astrophys. 408 (2003) L25-L28 | Subject: | astro-ph | Affiliation: | Laboratoire d’Astrophysique de Marseille, Laboratoire d’Astrophysique de l’Observatoire de Grenoble, Department of Physics and Astronomy, University of Wales, Cardiff, Observatoire du Mont Megantic et Departement de Physique, Univ | Abstract: | We present millimetre-line imaging of the Galactic HII region Sh 104. We show that it is surrounded by a ring of molecular gas and dust. Four large molecular condensations are regularly spaced around the ring. These condensations are themselves fragmented and contain several massive dense cores. A deeply embedded cluster is observed in the near IR towards the largest condensation. It contains at least one massive star ionizing an ultra-compact HII region. The Sh 104 region is a good illustration of the `collect and collapse’ model for star formation triggered by the expansion of an HII region. | Source: | arXiv, astro-ph/0309018 | Services: | Forum | Review | PDF | Favorites |
