Description

The Lupus I cloud complex is located in the collision zone between two expanding super-bubbles that are driven by the massive stars in two sub-groups of the ScoCen OB association. With a distance of just 150 pc, it represents the nearest example where we can study how such a collision process forms new dense clouds in the ISM. With multi-wavelength data available, we are able to condcut a comprehensive investigation of the physical structure of the cloud and its surroundings. We infer from these data the temperature and density distribution of the Lupus I cloud, its total mass, the small-scale structure, as well as the clump- and core-mass functions. The complete data set will be compared to detailed numerical models of expanding bubbles and colliding flows in the ISM that are developed by members of our team, and will advance our understanding of the effects of massive star feedback on the surrounding ISM.
