Description
The formation of stars plays a central role in the evolution of the interstellar medium of galaxies,
characterized by complex multi-scale mechanisms. In large hyperdense filaments generated by Galactic
collisions between molecular clouds, cloud fragments called dense cores form, then collapse, converting
their material in protostars. In order to survive this collapse and efficiently accrete gas, these protostars
eject material in the form of jets that carve protostellar outflows in the surrounding medium. With this thesis, we propose to study the formation of stars in regions observed at high angular resolution in the
frame of the ALMA-IMF large program. The scientific objectives are to characterize the cores and protostars
(multiplicity, mass, temperature, evolutionary stage, chemistry) and to understand the effects likely
to play a role in the determination of the final mass of the stars (kinematics/dynamics and magnetic
fields at all scales, ejection processes…).
