Conclusions
• Numerical simulations are illuminating the cluster picture of massive star
formation
• Feedback effects are coupled and must be studied individually and in concert
with each other
• Single stars may show variability in their HII regions during their pre-­‐main-­sequence
evolution
• Clusters are dominated by their most massive stars, with choice of prestellar
model having little impact on overall dynamics
• MHD and turbulence may play crucial roles in enhancing radiative feedback
Future Work
• We are combining realistic initial conditions with turbulence, MHD, ionizing
radiation and prestellar modeling to address:
disruption of molecular clouds, cloud lifetimes, cluster population dynamics
