Algorithmic comparisons of decaying, isothermal, supersonic turbulence
S. Kitsionas, C. Federrath, R. Klessen +10
Contradicting results have been reported in the literature with respect to the performance of the numerical techniques employed for the study of supersonic turbulence. We aim at ch…
Star Formation at Very Low Metallicity. V. The Greater Importance of Initial Conditions Compared to Metallicity Thresholds
A. -K. Jappsen, M. -M. Mac Low, S. C. O. Glover +2
The formation of the first stars out of metal-free gas appears to result in stars at least an order of magnitude more massive than in the present-day case. We here consider what co…
The formation of the first galaxies and the transition to low-mass star formation
Thomas H. Greif, Dominik R. G. Schleicher, Jarrett L. Johnson +6
The formation of the first galaxies at redshifts z ~ 10-15 signaled the transition from the simple initial state of the universe to one of ever increasing complexity. We here revie…
Massive Star Forming Regions: Turbulent Support or Global Collapse?
Enrique Vazquez-Semadeni, Javier Ballesteros-Paredes, Ralf S. Klessen +1
We present preliminary numerical evidence that the physical conditions in high-mass star forming regions can arise from global gravitational infall, with the velocity dispersions b…
Star Formation at Very Low Metallicity. IV. Fragmentation Does Not Depend on Metallicity for Cold Initial Conditions
Anne-Katharina Jappsen, Ralf S. Klessen, Simon C. O. Glover +1
Primordial star formation appears to result in stars at least an order of magnitude more massive than modern star formation. It has been proposed that the transition from primordia…
The Influence of Metallicity on Star Formation in Protogalaxies
A. -K. Jappsen, S. C. O. Glover, R. S. Klessen +1
In cold dark matter cosmological models, the first stars to form are believed to do so within small protogalaxies. We wish to understand how the evolution of these early protogalax…
