| 英文摘要 | The hyperluminous x-ray source (hlx-1, peak x-ray luminosity similar to 10(42) erg s(-1)) near the spiral galaxy eso 243-49, which underwent recurrent outbursts within a period of similar to 400 days, is possibly the best candidate for an intermediate mass black hole (imbh). the physical reason for this quasiperiodic variability is still unclear. we explore the possibility of radiation-pressure instability in the accretion disk by modeling the light curve of hlx-1, and find that it can roughly reproduce the duration, period, and amplitude of the recurrent outbursts in hlx-1 with an imbh of similar to 10(5) m-circle dot. our result provides a possible mechanism to explain the recurrent outbursts in hlx-1. we further find a universal correlation between the outburst duration and the bolometric luminosity for the black hole (bh) sources with a very broad mass range (e.g., x-ray binaries, hlx-1, and active galactic nuclei), which is roughly consistent with the prediction of radiation-pressure instability of the accretion disk. these results imply that "heartbeat" oscillations triggered by radiation-pressure instability may appear in different-scale bh systems. |
