摘要:

在过去的10年中,INTEGRAL为研究增积毫秒X射线天体(AMXP)做出了独特的贡献,发现了目前已知的14个此类源中的3个。除了增加已知AMXP的数量外,INTEGRAL还对20 keV以上的这些物体进行了观测,大大提高了我们对它们行为的理解。在这里,我们提出了一个审查的所有AMXPs与INTEGRAL观察到的,并讨论其行为在X射线域的物理解释。我们特别关注爆发过程中的光变曲线轮廓,以及时间,光谱和热核I型X射线爆发的属性。

英文摘要:

During the last 10 years, INTEGRAL made a unique contribution to the study of accreting millisecond X-ray pulsars (AMXPs), discovering three of the 14 sources now known of this class. Besides increasing the number of known AMXPs, INTEGRAL also carried out observations of these objects above 20 keV, substantially advancing our understanding of their behaviour. We present here a review of all the AMXPs observed with INTEGRAL and discuss the physical interpretation of their behaviour in the X-ray domain. We focus in particular on the lightcurve profile during outburst, as well as the timing, spectral, and thermonuclear type-I X-ray bursts properties.
