On the gravitational content of molecular clouds and their cores
Javier Ballesteros-Paredes, Gilberto C. Gómez, Bárbara Pichardo +1
(Abridged) The gravitational term for clouds and cores entering in the virial theorem is usually assumed to be equal to the gravitational energy, since the contribution to the grav…
The Nature of the Velocity Field in Molecular Clouds. I. The Non-Magnetic Case
Enrique Vazquez-Semadeni, Ricardo F. Gonzalez, Javier Ballesteros-Paredes +2
We present three numerical simulations of randomly driven, isothermal, non-magnetic, self-gravitating turbulence with different rms Mach numbers Ms and physical sizes L, but approx…
Massive Star Forming Regions: Turbulent Support or Global Collapse?
Enrique Vazquez-Semadeni, Javier Ballesteros-Paredes, Ralf S. Klessen +1
We present preliminary numerical evidence that the physical conditions in high-mass star forming regions can arise from global gravitational infall, with the velocity dispersions b…
