The large scale magnetic fields of thin accretion disks
Xinwu Cao, H. C. Spruit
Large scale magnetic field threading an accretion disk is a key ingredient in the jet formation model. The most attractive scenario for the origin of such a large scale field is th…
Long-Term evolution of Discs around Magnetic Stars
Caroline D'Angelo, Henk Spruit
We investigate the evolution of a thin viscous disc surrounding magnetic star, including the spindown of the star by the magnetic torques it exerts on the disc. The transition from…
High time resolution optical/X-ray cross-correlations for X-ray binaries: anti-correlations and rapid variability
Martin Durant, Tariq Shahbaz, Poshak Gandhi +9
Using simultaneous observations in X-rays and optical, we have performed a homogeneous analysis of the cross-correlation behaviours of four X-ray binaries: SWIFT J1753.5-0127, GX 3…
Rapid optical and X-ray timing observations of GX 339-4: multi-component optical variability in the low/hard state
P. Gandhi, V. S. Dhillon, M. Durant +9
A rapid timing analysis of VLT/ULTRACAM and RXTE observations of the black hole binary GX 339-4 in its 2007 low/hard state is presented. The optical light curves in the r', g' and…
