摘要：
The acceleration of LMXB 4 U 1820-30 derived from its orbital-period derivative ■ was supposed to be the evidence for an Intermediate-mass black hole(IMBH) in the Galactic globular cluster(GC) NGC 6624.However,we find that the anomalous ■ is mainly due to the gravitational wave emission,rather than the acceleration in cluster potential.Using the standard structure models of GCs,we simulate acceleration distributions for pulsars in the central region of the cluster.By fitting the acceleration of J1823-3021 A with the simulated distribution profiles(maximum values),it is suggested that an IMBH with mass ■ may reside in the cluster center.We further show that the second period derivative ■ of J1823-3021 A is probably due to the gravitational perturbation of a nearby star.
