Scientific paper

Based on our successful multi-line 12mm studies with the ATCA and (sub)mm observations with the SMA, we propose to observe the massive twin cores NGC6334I & I(N) in the 3mm continuum and the CH3CN(5_k-4_k) and HCN(1-0) line emission. The main goals are: (1) Studying the dust properties of these two enigmatic massive star-forming regions by combining the 3mm continuum data with the higher frequency (sub)mm continuum data obtained at the SMA. (2) The CH3CN data trace two orders of magnitude denser gas than our previous NH3 data, and we will be able to investigate the temperature structure of the denser gas. (3) HCN is known as a dense gas tracer but recent studies showed that it traces the outflow as well. Thus, we are going to investigate the core-outflow interaction with the HCN observations. (4) We will investigate chemical differences between the various evolutionary stages.
