Gravity or turbulence V: Star forming regions undergoing violent relaxation
Andrea Bonilla-Barroso, J. Ballesteros-Paredes, Jesus Hernández +6
Using numerical simulations of the formation and evolution of stellar clusters within molecular clouds, we show that the stars in clusters formed within collapsing molecular cloud…
The Role of Gravity in Producing Power-Law Mass Functions
Aleksandra Kuznetsova, Lee Hartmann, Fabian Heitsch +1
Numerical simulations of star formation have found that a power-law mass function can develop at high masses. In a previous paper, we employed isothermal simulations which created…
On estimating angular momenta of infalling protostellar cores from observations
Shangjia Zhang, Lee Hartmann, Manuel Zamora +1
We use numerical simulations of molecular cloud formation in the colliding flow scenario to investigate the reliability of observational estimates of the angular momenta of early-s…
Kinematics and Structure of Star-forming Regions: Insights from Cold Collapse Models
Aleksandra Kuznetsova, Lee Hartmann, Javier Ballesteros-Paredes
The origin of the observed morphological and kinematic substructure of young star forming regions is a matter of debate. We offer a new analysis of data from simulations of globall…
Gravitational Focusing and the Star Cluster Initial Mass Function
Aleksandra Kuznetsova, Lee Hartmann, Andreas Burkert
We discuss the possibility that gravitational focusing, is responsible for the power-law mass function of star clusters . This power law can be produced a…
Bondi-Hoyle-Littleton accretion and the upper mass stellar IMF
Javier Ballesteros-Paredes, Lee W. Hartmann, Nadia Perez-Goytia +1
We report on a series of numerical simulations of gas clouds with self-gravity forming sink particles, adopting an isothermal equation of state to isolate the effects of gravity fr…
