How to explain different variability classes of XRBs, e.g. GRS 1915+105?

Recent numerical simulations show that the inner part of the disk seems to oscillate in presence of a Large scale magnetic field or when the disk is in MAD state. So, can we correlate this sort of behaviour with the variability of the source?

Strong Magnetic field inside the compact object plays the crucial role for understanding the variable x-ray burst. Change in internal structure due to the presence of superfluidity, superconductivity and external accretion also are responsible for this variable x-ray burst. What I understand that we have to consider these three first and then to compare with the simulation where the effect is changing, finally we will be able to understand what is actually going on.
Simulation can help us to know the magnitude of possible change and its location to find out inside the compact object.

We present results of a monitoring campaign of the high-mass X-ray binary system 4U 1700-37/HD 153919, carried out with XMM-Newton in February 2001. The system was observed at four orbital phase intervals, covering 37% of one 3.41-day orbit. The lightcurve includes strong flares, commonly observed in this source. We focus on three epochs in which t...
