The early phases of massive stellar feedback: confronting observations radiation pressure, winds and SNe with radiative MHD simulations
Eric Pellegrini ITA/ZAH, Heidelberg, DE | |

Observational constraints of feedback from massive have progressed to
quantitative measurements of the most dynamically important physical
processes: radiation pressure, stellar wind and SNe.
However, observations are limited to only a few massive star forming
regions, such as 30 Dor, which only offer a snapshot in time and after
significant evolution.
I will present the first 3D radiative MHD simulations to account for all significant stellar feedback mechanisms and chemistry. We reproduce the evolution of a 30Dor type environment (0.1 to 100pc) for the first 10Myr, and provide diagnostics of the contribution of each physical processes to the dynamics and chemistry. I will discuss these results in the context of environments ranging from embedded massive clusters to high SFRD galaxies. | |
