Effects of Varying the Three-Body Molecular Hydrogen Formation Rate in Primordial Star Formation
Matthew J. Turk, Paul Clark, S. C. O. Glover +4
The transformation of atomic hydrogen to molecular hydrogen through three-body reactions is a crucial stage in the collapse of primordial, metal-free halos, where the first generat…
Stellar and substellar initial mass function: a model that implements gravoturbulent fragmentation and accretion
Todor Veltchev, Ralf S. Klessen, Paul C. Clark
In this work, we derive the stellar initial mass function (IMF) from the superposition of mass distributions of dense cores, generated through gravoturbulent fragmentation of unsta…
A quantification of the non-spherical geometry and accretion of collapsing cores
Rowan J. Smith, Simon C. O. Glover, Ian A. Bonnell +2
We present the first detailed classification of the structures of Class 0 cores in a high resolution simulation of a giant molecular cloud. The simulated cloud contains 10^4 solar…
The efficiency of star formation in clustered and distributed regions
Ian A. Bonnell, Rowan J. Smith, Paul C. Clark +1
We investigate the formation of both clustered and distributed populations of young stars in a single molecular cloud. We present a numerical simulation of a 10,000 solar mass elon…
The Effect of Environment on Massive Star Formation
Rowan J Smith, Paul C. Clark, Simon C. O. Glover +2
In this contribution we review our recent numerical work discussing the essential role of the local cluster environment in assembling massive stars. First we show that massive star…
Protostellar collapse and fragmentation using an MHD GADGET
Florian Bürzle, Paul C. Clark, Federico Stasyszyn +4
Although the influence of magnetic fields is regarded as vital in the star formation process, only a few magnetohydrodynamics (MHD) simulations have been performed on this subject…
Fragmentation in turbulent primordial gas
S. C. O. Glover, P. C. Clark, R. S. Klessen +1
We report results from numerical simulations of star formation in the early universe that focus on the role of subsonic turbulence, and investigate whether it can induce fragmentat…
Implementing and comparing sink particles in AMR and SPH
Christoph Federrath, Robi Banerjee, Daniel Seifried +2
We implemented sink particles in the Adaptive Mesh Refinement (AMR) code FLASH to model the gravitational collapse and accretion in turbulent molecular clouds and cores. Sink parti…
Gravitational fragmentation in turbulent primordial gas and the initial mass function of Population III stars
Paul C. Clark, Simon C. O. Glover, Ralf S. Klessen +1
We report results from numerical simulations of star formation in the early universe that focus on the dynamical behavior of metal-free gas under different initial and environmenta…
Modeling Collapse and Accretion in Turbulent Gas Clouds: Implementation and Comparison of Sink Particles in AMR and SPH
Christoph Federrath, Robi Banerjee, Paul C. Clark +1
We implemented sink particles in the adaptive mesh refinement (AMR) hydrodynamics code FLASH. Sink particles are created in regions of local gravitational collapse, and their traje…
