Massive Infrared-Quiet Dense Cores: Unveiling the Initial Conditions of High-Mass Star Formation
Résumé
As Th. Henning said at the conference, cold precursors of high-mass stars are now ''hot topics''. We here propose some observational criteria to identify massive infrared-quiet dense cores which can host the high-mass analogs of Class~0 protostars and pre-stellar condensations. We also show how far-infrared to millimeter imaging surveys of entire complexes forming OB stars are starting to unveil the initial conditions of high-mass star formation.
