The role of jets in the formation of planets, stars, and galaxies
Ralph E. Pudritz, Robi Banerjee, Rachid Ouyed
Astrophysical jets are associated with the formation of young stars of all masses, stellar and massive black holes, and perhaps even with the formation of massive planets. Their ro…
Filaments, Collapse and Outflows in Massive Star Formation
Robi Banerjee, Ralph E. Pudritz
We present results from our numerical simulations of collapsing massive molecular cloud cores. These numerical calculations show that massive stars assemble quickly with mass accre…
Understanding the Spins of Young Stars
Sean Matt, Ralph E. Pudritz
We review the theoretical efforts to understand why pre-main-sequence stars spin much more slowly than expected. The first idea put forward was that massive stellar winds may remov…
Star Formation: 3D Collapse of Turbulent Cloud Cores
M. A. Reid, R. E. Pudritz, J. Wadsley
We have performed fully 3D simulations of the collapse of molecular cloud cores which obey the logatropic equation of state. By following the collapse of these cores from states of…
Fragmentation and Collapse of Turbulent Molecular Clouds
David A. Tilley, Ralph E. Pudritz, James Wadsley
We performed simulations of self-gravitating hydrodynamic turbulence to model the formation of filaments, clumps and cores in molecular clouds. We find that when the mass on the in…
A New Model for Filamentary Molecular Clouds
Jason D. Fiege, Ralph E. Pudritz
We develop a theory for filamentary molecular clouds including the effects of ordered magnetic fields, and external pressure. We first derive a form of the virial equation appropri…
