Scientific paper

We will present results from new sub-arcsecond ( 700 AU) resolution Submillimeter Array observations of the massive Galactic "protocluster" NGC6334I. These data reveal at least four massive protostars in various stages of evolution including an ultra compact HII region, two hot cores with prodigious molecular line emission, and an enigmatic line-free but warm dust source. This region provides an excellent laboratory for exploring the formation of OB stellar clusters, where most massive stars are born. The very high dust continuum optical depths exhibited by the members of this protocluster suggest that future studies with ALMA and EVLA will need to be carried out longward of 1mm to probe the kinematics of the innermost regions of individual massive protostars.
