Global collapse of molecular clouds as a formation mechanism for the most massive stars
The relative importance of primordial molecular cloud fragmentation versus large-scale
accretion still remains to be assessed in the context of massive core/star formation. Studying …

Radiation-hydrodynamic simulations of collapse and fragmentation in massive protostellar cores
We simulate the early stages of the evolution of turbulent, virialized, high-mass protostellar
cores, with primary attention to how cores fragment and whether they form a small or large …

Circumventing the radiation pressure barrier in the formation of massive stars via disk accretion
We present radiation hydrodynamic simulations of the collapse of massive pre-stellar cores.
We treat frequency-dependent radiative feedback from stellar evolution and accretion …
