| Abstract: |
Do massive stars form in isolation? Most of the candidates are turned down as runaways from large stellar systems. Possibly the best way to identify a truly isolated massive star is while it forms, when the surrounding gas appears as a compact H II region. In this context we present the first detailed study of the compact H II region SMC-N33 (size : 2.2 pc). We recently found that this H II region is powered by a single massive star (O6.5-O7 V), which is not related to any star cluster. Specifically, we do not find any traces of clustering around N33 on scales larger than 10″ (∼ 3 pc). We also verify that N33 is not a member of any large stellar association. Under these circumstances, N33 is therefore attractive because it represents a remarkable candidate of isolated massive-star formation in the SMC. |
