Filamentary fragmentation in a turbulent medium
S. D. Clarke, A. P. Whitworth, A. Duarte-Cabral +1
We present the results of smoothed particle hydrodynamic simulations investigating the evolution and fragmentation of filaments that are accreting from a turbulent medium. We show…
Perturbation growth in accreting filaments
Seamus D. Clarke, Anthony P. Whitworth, David A. Hubber
We use smoothed particle hydrodynamic simulations to investigate the growth of perturbations in infinitely long, initially sub-critical but accreting filaments. The growth of these…
First Investigation of the Combined Impact of Ionizing Radiation and Momentum Winds from a Massive Star on a Self-Gravitating Core
Judith Ngoumou, David Hubber, James E. Dale +1
Massive stars shape the surrounding ISM by emitting ionizing photons and ejecting material through stellar winds. To study the impact of the momentum from the wind of a massive sta…
Clumps and triggered star formation in ionised molecular clouds
S. Walch, A. P. Whitworth, T. G. Bisbas +2
Infrared shells and bubbles are ubiquitous in the Galaxy and can generally be associated with HII regions formed around young, massive stars. In this paper, we use high-resolution…
Episodic accretion, protostellar radiative feedback, and their role in low-mass star formation
Dimitris Stamatellos, Anthony P. Whitworth, David A. Hubber
Protostars grow in mass by accreting material through their discs, and this accretion is initially their main source of luminosity. The resulting radiative feedback heats the envir…
Dispersal of molecular clouds by ionising radiation
S. Walch, A. P. Whitworth, T. Bisbas +2
The role of feedback from massive stars is believed to be a key element in the evolution of molecular clouds. We use high-resolution 3D SPH simulations to explore the dynamical eff…
