We propose to image a small sample of 10 millimetre continuum sources identified in a 1.2mm continuum survey by Hill et al. (2005). These sources are devoid of typical indications of massive star formation such as methanol maser and radio continuum sources. Subsequent submillimetre continuum observations, Parkes ammonia observations and spectral energy distribution analysis indicate that these mm-only sources have characteristics similar to sources known to be forming massive stars, making them excellent candidates for early stage protostars. We are now proposing to image a small sample of these protostar candidates in 3 and 7mm continuum using the CABB system on the ATCA. These observations will allow resolution of the cores into individual components, study of their spectral index and their evolution; determination of their radial density structure and insight into the conditions required for fast protostellar collapse; determination of the clump mass fraction of the main mm-only complex as well as the individual components; in addition to providing insight into the turbulence of the cores. Ultimately these observations allow characterisation of the mm-only cores and insight into their star formation status and evolution.
