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…
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 fi…
Gravity or turbulence? VI. The physics behind the Kennicutt-Schmidt relations
Javier Ballesteros-Paredes, Manuel Zamora-Avilés, Carlos Román-Zúñiga +6
We explain the large variety of star formation laws in terms of one single, simple law that can be inferred from the definition of the star formation rate and basic algebra. The re…
Unveiling two expanding stellar groups formed through violent relaxation in The Lagoon Nebula Cluster
A. Bonilla-Barroso, J. Ballesteros-Paredes, J. Hernández +2
The current kinematic state of young stellar clusters can give clues on their actual dynamical state and origin. In this contribution, we use Gaia DR3 data of the Lagoon Nebula Clu…
Why most molecular clouds are gravitationally dominated
Laura Ramírez-Galeano, Javier Ballesteros-Paredes, Rowan Smith +2
Observational and theoretical evidence suggests that a substantial population of molecular clouds (MCs) appear to be unbound, dominated by turbulent motions. However, these estimat…
What is the physics behind the Larson mass-size relation?
Javier Ballesteros-Paredes, Carlos Román-Zúñiga, Quentin Salomé +2
Different studies have reported a power-law mass-size relation for ensembles of molecular clouds. In the case of nearby clouds, the index of the power-law is cl…
The magnetic field structure in molecular cloud filaments
Gilberto C. Gomez, Enrique Vazquez-Semadeni, Manuel Zamora-Aviles
We explore the structure of magnetic field lines in and around filaments in simulations of molecular clouds undergoing global, multi-scale gravitational collapse. In these simulati…
Cluster Assembly in Hierarchically Collapsing Clouds
Enrique Vazquez-Semadeni, Alejandro Gonzalez-Samaniego, Manuel Zamora-Aviles +1
We discuss the mechanism of cluster formation in hierarchically collapsing molecular clouds. Recent evidence, both observational and numerical, suggests that molecular clouds (MCs)…
An Evolutionary Model for Collapsing Molecular Clouds and Their Star Formation Activity. II. Mass Dependence of the Star Formation Rate
Manuel Zamora-Avilés, Enrique Vázquez-Semadeni
We discuss the dependence of various properties of the star formation rate (SFR) and efficiency (SFE) in molecular clouds (MCs) on the maximum mass reached by the clouds, based on…
An Evolutionary Model for Collapsing Molecular Clouds and Their Star Formation Activity
Manuel Zamora-Aviles, Enrique Vázquez-Semadeni, Pedro Colín
We present an idealized, semi-empirical model for the evolution of gravitationally contracting molecular clouds (MCs) and their star formation rate (SFR) and efficiency (SFE). The…
