On the origin of γ-ray emission in η Carina
S. Ohm, V. Zabalza, J. A. Hinton +1
η Car is the only colliding-wind binary for which high-energy γ rays are detected. Although the physical conditions in the shock region change on timescales of hours to days, the v…
The 2.35 year itch of Cygnus OB2#9 III. X-ray and radio emission analysis based on three dimensional hydrodynamical modelling
E. R. Parkin, J. M. Pittard, Y. Nazé +1
X-ray and radio data recently acquired as part of a project to study Cyg OB2#9 are used to constrain physical models of the binary system, providing in-depth knowledge about the wi…
Global simulations of magnetorotational turbulence III: influence of field configuration and mass injection
E. R. Parkin
The stresses produced by magnetorotational turbulence can provide effective angular momentum transport in accretion disks. However, questions remain about the ability of simulated…
Global simulations of magnetorotational turbulence II: turbulent energetics
E. R. Parkin
Magnetorotational turbulence draws its energy from gravity and ultimately releases it via dissipation. However, the quantitative details of this energy flow have not been assessed…
Long time-scale variability of X-ray binaries with late type giant companions
E. Filippova, M. Revnivtsev, E. R. Parkin
In this paper we propose and examine a physical mechanism which can lead to the generation of noise in the mass accretion rate of low mass X-ray binaries on time-scales comparable…
Global simulations of magnetorotational turbulence I: convergence and the quasi-steady state
E. R. Parkin, G. V. Bicknell
Magnetorotational turbulence provides a viable mechanism for angular momentum transport in accretion disks. We present global, three dimensional (3D), MHD accretion disk simulation…
