Comparing simulations of ionisation triggered star formation and observations in RCW 120
S. Walch, A. Whitworth, T. Bisbas +2
Massive clumps within the swept-up shells of bubbles, like that surrounding the galactic HII region RCW 120, have been interpreted in terms of the Collect and Collapse (C&C) mechan…
The influence of the turbulent perturbation scale on prestellar core fragmentation and disk formation
S. Walch, A. P. Whitworth, P. Girichidis
The collapse of weakly turbulent prestellar cores is a critical stage in the process of star formation. Being highly non-linear and stochastic, the outcome of collapse can only be…
Radiation driven implosion and triggered star formation
Thomas G. Bisbas, Richard Wunsch, Anthony P. Whitworth +2
We present simulations of initially stable isothermal clouds exposed to ionising radiation from a discrete external source, and identify the conditions that lead to radiatively dri…
Flow-Driven Cloud Formation and Fragmentation: Results From Eulerian and Lagrangian Simulations
Fabian Heitsch, Thorsten Naab, Stefanie Walch
The fragmentation of shocked flows in a thermally bistable medium provides a natural mechanism to form turbulent cold clouds as precursors to molecular clouds. Yet because of the l…
The turbulent fragmentation of the interstellar medium: The impact of metallicity on global star formation
S. Walch, R. Wuensch, A. Burkert +2
We study the influence of gas metallicity, turbulence, and non-equilibrium chemistry on the evolution of the two-phase interstellar medium (warm and cold atomic phases), and thereb…
