Simulating Giant Molecular Clouds with individual star formation
David Guszejnov UT Austin, Austin, US | |
| The main engines of star formation in the local Universe are giant molecular clouds (GMCs) with masses of 104-106 Msun. So far no radiation-hydro simulation has managed to follow the evolution of such a cloud throughout its lifetime while also resolving the formation of individual low-mass stars. We introduce the STARFORGE simulation suite using the GIZMO code, the first set of simulations with the physics and dynamic range to provide a self-consistent picture of a star forming GMC disrupted by long-range feedback. We will present runs with progressively more complicated physics, starting from pure isothermal MHD, then cooling physics, dust, protostellar heating and outflows and show the role each of these physical processes play in determining the IMF. | |

This simulation resolves a dynamic range from 50 pc down to 30 AU, making it the largest resolved star formation simulation to date. | |
