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…
Cluster Formation and the ISM
Ralph E. Pudritz, Jason D. Fiege
We review the physics of star formation, and its links with the state of the ISM in galaxies. Current obervations indicate that the preferred mode of star formation is clustered. G…
Disk Winds and the Accretion--Outflow Connection
Arieh Konigl, Ralph E. Pudritz
We review recent observational and theoretical results on the relationship between circumstellar accretion disks and jets in young stellar objects. We then present a theoretical fr…
Observations and Theory of Star Cluster Formation
B. G. Elmegreen, Y. N. Efremov, R. E. Pudritz +1
Young stars form on a wide range of scales, producing aggregates and clusters with various degrees of gravitational self-binding. The loose aggregates have a hierarchical structure…
