Gravity or turbulence? VII. The Schmidt-Kennicutt law, the star formation efficiency, and the mass density of clusters from gravitational collapse rather than turbulent support
Manuel Zamora-Aviles, Vianey Camacho, Javier Ballesteros-Paredes +7
We explore the Schmidt-Kennicutt (SK) relations and the star formation efficiency per free-fall time (), mirroring observational studies, in numerical simulations of f…

The Turbulent Support (TS) and Global Hierarchical Collapse (GHC) models for molecular clouds compared. Differences, convergence, and myths
Enrique Vázquez-Semadeni, Aina Palau, Gilberto C. Gómez +8
We provide a detailed comparison between the ``turbulent support'' (TS) and ``global hierarchical collapse'' (GHC) models for molecular clouds and star formation, their respective…

Dynamical heating of newborn stars driven by accretion-induced orbital tightening
Vianey Camacho, Andrea Bonilla-Barroso, Javier Ballesteros-Paredes +2
In previous works, we have shown that stars in the Orion and the Lagoon Nebula Clusters, and simulations of collapsing clouds, exhibit constant velocity dispersion as a function of…
