| Abstract | We made a phase-resolved timing analysis of GRS 1915+105 in its rho state and obtained detailed rho cycle evolutions of the frequency, amplitude, and coherence of the low-frequency quasi-periodic oscillation (LFQPO). We combined our timing results with the spectral study by Neilsen et al. to perform an elaborate comparison analysis. Our analyses show that the LFQPO frequency does not scale with the inner disk radius, but it is related to the spectral index, indicating a possible correlation between the LFQPO and the corona. The LFQPO amplitude spectrum and other results are naturally explained by tying the LFQPO to the corona. The similarities of the spectra of variability parameters between the LFQPOs from rho state and those from more steady states indicate that the LFQPOs of GRS 1915+105 in very different states seem to share the same origin. |
