Influence of the turbulent magnetic pressure on isothermal jet emitting disks
N. Zimniak, J. Ferreira, J. Jacquemin-Ide
The theory of jet emitting disks (JEDs) provides a mathematical framework for a self-consistent treatment of steady-state accretion and ejection. A large-scale vertical magnetic fi…
Magnetically-driven jets and winds from weakly magnetized accretion disks
J. Jacquemin-Ide, J. Ferreira, G. Lesur
Semi-analytical models of disk outflows have successfully described magnetically-driven, self-confined super-Alfvénic jets from near Keplerian accretion disks. These Jet Emitting D…
A unified accretion-ejection paradigm for black hole X-ray binaries. IV. Replication of the 2010--2011 activity cycle of GX 339-4
G. Marcel, J. Ferreira, M. Clavel +8
Transients XrB exhibit different spectral shapes during their evolution. In luminosity-color diagrams, their X-ray behavior forms unexplained q-shaped cycles. We proposed a framewo…
A unified accretion-ejection paradigm for black hole X-ray binaries. III. Spectral signatures of hybrid disk configurations
G. Marcel, J. Ferreira, P-O. Petrucci +9
It has been suggested that the cycles of activity of X-ray Binaries (XrB) are triggered by a switch in the dominant disk torque responsible for accretion (paper I). As the disk acc…
Evolution of the reverberation lag in GX 339-4 at the end of an outburst
B. De Marco, G. Ponti, P. O. Petrucci +13
We studied X-ray reverberation lags in the BHXRB GX 339-4 at the end of the 2014-2015 outburst. We analysed data from a XMM-Newton campaign covering the end of the transition from…
