摘要
We demonstrate that the four high-frequency QPOs observed in GRS 1915 + 105 can be interpreted as the oscillation modes on disks that non-linearly and resonantly interact with a warp. The warp is assumed to be a low-frequency global pattern on the disk. This identification suggests that the relevant mass, M, and spin parameter, a, are M = 13-14 M-circle dot and a = 0-0.15.
