Filamentary collapse flow in molecular clouds
Raúl Naranjo-Romero, Enrique Vázquez-Semadeni, Robert M. Loughnane
We present idealized numerical simulations of prestellar gravitational collapse of a moderate initial filamentary perturbation with an additional central ellipsoidal enhancement (a…
Non-adiabatic turbulence driving during gravitational collapse
Rubén Guerrero-Gamboa, Enrique Vázquez-Semadeni
We investigate the generation of turbulence during the prestellar gravitational contraction of a turbulent spherical core. We define the ratio of the one-dimensional turbulent…
Density profile evolution during prestellar core collapse: Collapse starts at the large scale
Gilberto C. Gómez, Enrique Vázquez-Semadeni, Aina Palau
We study the gravitationally-dominated, accretion-driven evolution of a prestellar core. In our model, as the core's density increases, it remains immersed in a constant-density en…
Zooming in on Individual Star Formation: Low- and High-mass Stars
Anna L. Rosen, Stella S. R. Offner, Sarah I. Sadavoy +3
Star formation is a multi-scale, multi-physics problem ranging from the size scale of molecular clouds (10s pc) down to the size scales of dense prestellar cores (0.1 p…
Simultaneous evolution of the virial parameter and star formation rate in molecular clumps undergoing global hierarchical collapse
Vianey Camacho, Enrique Vázquez-Semadeni, Aina Palau +2
We compare dense clumps and cores in a numerical simulation of molecular clouds (MCs) undergoing global hierarchical collapse (GHC) to observations in two MCs at different evolutio…
Global Hierarchical Collapse In Molecular Clouds. Towards a Comprehensive Scenario
Enrique Vázquez-Semadeni, Aina Palau, Javier Ballesteros-Paredes +2
We present a unified description of the scenario of Global Hierarchical Collapse and fragmentation (GHC) in molecular clouds (MCs), owing to the continuous decrease of the average…
