Be/X射线双星是中子星高质量X射线双星中最大且最多样化的子群。这些系统的特点是快速旋转的Be星被星际吸积盘环绕，该吸积盘是物质 accreted到强磁化中子星的主要储存库。少数Be/X射线双星持续活跃，多数表现为硬X射线瞬变源，仅在X射线爆发时可探测到。本综述综合了当前对其在光学和X射线波长丰富现象学的理解，重点关注从秒到年时间尺度上的变异性。
英文摘要
Be/X-ray binaries constitute the largest and most diverse subgroup of neutron star high-mass X-ray binaries. These systems feature a rapidly rotating Be star surrounded by a circumstellar decretion disk that serves as the primary reservoir of accreted matter onto a strongly magnetized neutron star. While a few Be/X-ray binaries remain persistently active, the majority manifest as hard X-ray transient sources, becoming detectable only during X-ray outbursts. This review synthesizes current understanding of their rich phenomenology across optical and X-ray wavelengths, focusing on variability ocurring over timescales that span from seconds to years.
