On Be/X-ray binaries with an intermediate-mass black hole |

| Abstract: | We adopt the tidal truncation model proposed by Negueruela and Okazaki for Be/X-ray binaries to investigate the influence of intermediate-mass black holes(IMBHs)on Be-star disks.We show that the viscous decretion disks around Be stars are generally truncated ineffectively under the tidal force of IMBHs.Combining this with observations of Be/X-ray binaries,we suggest that Be/IMBH X-ray binaries may appear as recurrent luminous X-ray transients with quasi-periodic X-ray outbursts. |
