Abstract
In the original language
Oscillatory behavior in the total flux emitted from both single and double torus structures was observed in our general relativistic magnetohydrodynamical simulations performed using the High-Accuracy Astrophysical Relativistic MHD code. These features became evident during a ray tracing conducted with the postprocessing tool IPOLE. Fast Fourier transform analysis of the resulting light curves revealed the presence of dominant frequency components. Two dominant frequencies are observed for interacting counterrotating tori, demonstrating a frequency ratio similar to 3 : 2 that is generated during the most intensive interaction of the tori. For corotating tori, the situation is more complex. There are indications that increasing magnetic field intensity enlarges the number of observed oscillations.
