High-Excitation Blobs and isolated massive star formation in the Magellanic Clouds



Romain SELIER

Observatoire de Paris/LERMA



Résumé : Accurate physical parameters of newborn massive stars are essential to understand their formation. The rare class of compact HII regions in the Magellanic Clouds, called "High-Excitation Blobs" (HEBs), provide a unique opportunity to obtain these information. Indeed these small objects (4 to 10", 1 to 3 pc, in diameter) harbor the youngest massive stars detectable through IR and optical techniques. I shall present an overview of the results we obtained recently on two HEBs in the Small Magellanic Cloud. In particular I shall discuss an interesting case of isolated massive star formation, a topic actively debated in current massive star formation studies.
