Description
While OB stars are critical for modern Astrophysics, the physical process leading to their formation is among the least understood. The reason for this disappointing fact is twofold. (1)Observationally, OB stars, which have masses 10 to 100 times that of our Sun, are rare (rarer than solar-type stars) and their earliest phases, called proto-OB stars, are difficult to study. (2)Theoretically, the multi-scale compressible MHD models which are used to describe the formation of solar-type stars complicate even further with the introduction of the physical and chemical feedback processes of OB stars. As a direct consequence of their rarity, proto-OB stars must be surveyed across the whole Galaxy (area foreseen of several hundreds of square degrees) as well as with high-spatial resolution tools (sub-0.1 parsec scales and therefore sub-arcsecond studies). It's now time to take advantage of several imaging surveys that will soon be performed in the critical far-infrared to submillimeter domain to (1)locate these very rare proto-OB stars, (2)assess the importance of triggered OB star formation, and (3)constrain the physical process at the origin of the formation of OB stars. All these studies will be done in the perspective of the upcoming advent of the ALMA interferometer. In the 'PROBES' project, we are asking for financial support in order to be able to increase the activity of our groups (LAB Bordeaux, AIM/SAp Saclay, and LAM Marseille) and reinforce our leadership on the earliest phases of OB star formation.
