Description
We are presenting here a study of the cold dust in the close environs of the ring nebula Gum 31. We aim at deriving the physical properties of the molecular gas and dust associated with the nebula, and investigating its correlation with the star formation in the region, that was probably triggered by the expansion of the ionization front against its environment. We make use of 870um emission data obtained with the Large APEX Bolometer Camera (LABOCA) to map the dust emission. The 870um emission provides an excellent probe of mass and density of dense molecular clouds. The obtained LABOCA image was compared to archival infrared, radio continuum, and optical images.
