| Abstract: |
To reveal an extensive image of dense molecular gas (nH_2 >≈ 104-5 cm-3) of Orion B giant molecular cloud, we have carried out systematic observations in H13CO+ (J = 1--0) based on the C18O (J = 1--0) observations. We have identified 19 C18O clumps and found that C18O molecular column density is a good indicator of star formation. The eleven H13CO+ clumps are classified clearly into massive clumps or small clumps by their mass, and these two-types show different star formation modes. Detailed observations were also made toward some of the H13CO+ clumps with the Nobeyama 45m telescope. |
