英文摘要 | We investigate the correlation between the frequencies of twin kilohertz quasi-periodic oscillations (kHz QPOs) and neutron star (NS) spins in low-mass X-ray binaries (LMXBs), based on the data sets of 12 sources with simultaneously detected twin kHz QPOs and NS spins, and find that the histogram of the ratio between the frequency difference of twin kHz QPOs (Delta nu nu(2) - nu(1)) and NS spin nu(s) shows a non-uniform distribution with a gap at Delta nu/nu(s) similar to 0.65. We try to classify the 12 sources into two categories according to this gap: (I) slow rotators with |
