Virial theorem analysis of 3D numerical simulations of MHD self-gravitating turbulence
Mohsen Shadmehri, Enrique Vazquez-Semadeni, Javier Ballesteros-Paredes
We discuss the virial balance of all members of a cloud ensemble in numerical simulations of self-gravitating MHD turbulence. We first discuss the choice of reference frame for eva…
Physical vs. Observational Properties of Clouds in Turbulent Molecular Cloud Models
Javier Ballesteros-Paredes, Mordecai-M. Mac Low
We examine how well the physical properties of clumps in turbulent molecular clouds can be determined by measurements of observed clump structures. We compare simulated observation…
Rapid Formation of Molecular Clouds and Stars in the Solar Neighborhood
Lee Hartmann, Javier Ballesteros-Paredes, Edwin A. Bergin
Observations of both star-forming regions and young, gas-free stellar associations indicate that most nearby molecular clouds form stars only over a short time span before dispersa…
