Measuring stellar magnetic helicity density
K. Lund, M. Jardine, L. T. Lehmann +10
Helicity is a fundamental property of a magnetic field but to date it has only been possible to observe its evolution in one star - the Sun. In this paper we provide a simple techn…
Radiation hydrodynamic simulations of massive star formation via gravitationally trapped HII regions - Spherically symmetric ionised accretion flows
Kristin Lund, Kenneth Wood, Diego Falceta-Gonçalves +5
This paper investigates the gravitational trapping of HII regions predicted by steady-state analysis using radiation hydrodynamical simulations. We present idealised spherically sy…
Testing the stability of supersonic ionized Bondi accretion flows with radiation hydrodynamics
Bert Vandenbroucke, Nina S. Sartorio, Kenneth Wood +6
We investigate the general stability of 1D spherically symmetric ionized Bondi accretion onto a massive object in the specific context of accretion onto a young stellar object. We…
The formation of high-mass binary star systems
Kristin Lund, Ian Bonnell
We develop a semi-analytic model to investigate how accretion onto wide low-mass binary stars can result in a close high-mass binary system. The key ingredient is to allow mass acc…
