| 英文摘要 | We performed a global study on the timing and spectral properties of type-b quasi-periodic oscillations (qpos) in the outbursts of black hole x-ray binaries. the sample is built based on the observations of rossi x-ray timing explorer (rxte), via searching in the literature in rxte era for all the identified type-b qpos. to enlarge the sample, we also investigated some type-b qpos that are reported but not yet fully identified. regarding to the time lag and hard/soft flux ratio, we found that the sources with type-b qpos behave in two subgroups. in one subgroup, type-b qpo shows a hard time lag that first decreases and then reverse into a soft time lag along with softening of the energy spectrum. in the other subgroup, type-b qpos distribute only in a small region with hard time lag and relatively soft hardness. these findings may be understood with a diversity of the homogeneity showing up for the hot inner flow of different sources. we confirm the universality of a positive relation between the type-b qpo frequency and the hard component luminosity in different sources. we explain the results by considering that the type-b qpo photons are produced in the inner accretion flow around the central black hole, under a local eddington limit. using this relationship, we derived a mass estimation of 9.3-27.1 m-circle dot for the black hole in h 1743-322. |
