There is no generally accepted evolutionary scheme for high mass star formation yet. A simple approach to address this problem is to cover several of the known stages during the formation of massive stars in the same cloud and then investigate their properties trying to construct an evolutionary sequence. Here we present such a project conducted with complementary APEX and ATCA observations. These observations show a compact and bright single hot core in the G327.3-0.6 region on a 0.03 pc scale with a mass of 500 M and 0.5-1.5 10 5 L. Additionally a clumpy filament is seen in N 2 H + . Together with cm continuum observations, the data reveal like pearls on a string several stages of massive star formation, with likely the youngest stages hiding in the cold N 2 H + cores analysed with a multilevel study of the APEX and ATCA observations. © 2007 Springer Science+Business Media B.V.
