Molecular cloud structure and star formation in the W43 complex

摘要

The W43 region is one of the most massive star forming regions in our Galaxy. It is subject to a large IRAM 30m project that observes high spectral resolution maps of the complete complex in the ~(13)CO (2-1) and C~(18)O (2-1) lines. We find a variety of different sources of which we calculate excitation temperature, H_2 column density and mass. We find the total mass of dense clouds in the complex to be 1.2 × 10~6 M_⊙.
