Symposium S10  27-28 June 2019

Feedback during the star formation process

Aims and scope

The process of star formation is a multi-scale, highly non-linear process. It involves a complex interplay between interstellar medium (ISM) gas, magnetic fields, turbulence, radiation, chemistry, and cosmic rays. The rapid rise of computation power now allows to combine these processes in multi-component simulations at large galactic scales as well as scales of young stellar objects (YSO). The symposium aims at providing a state-of-the-art view of this rapidly evolving field. The program describes the scale-dependent physics of star formation, i.e. from the smallest YSO scales to the galactic scales and even extragalactic scales. Session 1 addresses the physics of the different feedback mechanisms throughout the stellar evolution, from birth to death, as well as the stellar mass. It also describes their effects at molecular clouds scales on the star formation efficiency. Session 2 is dedicated to the largest scales, how these feedback affect the galactic star formation rate ? and finally a special session discusses star formation in other galaxies also accounting for the back-reaction of the activity in the central region and the star formation history impact for cosmology.


  • Session 1: Stellar feedback physics -- session 1.1: YSO back reaction (jet/outflow, radiative heating) -- session 1.2: Effect of main sequence stars (stellar winds, ionization) -- session 1.3: Supernova feedback --
  • Session 2 : Star formation rate in galaxies -- session 2.1: Galactic evolution and other feedback mechanisms (AGN, accretion/winds) -- session 2.2: The galactic star formation rate -- session 2.3: Star formation in other galaxies and its impact across cosmic time --
