  1. 中子星X射线双星的观测研究

  2. 大质量X射线双星 • 持续源 • OB supergiant HMXBs Lx>1036 erg/s • 暂现源 • Be/XRBs Lx~1033-1037 erg/s • Supergiant Fast X-ray Transients (SFXTs) Lx~1033-1037 erg/s

  3. 研究目标:通过对吸积脉冲星的观测,研究中子星的磁场和吸积流的相互作用研究目标:通过对吸积脉冲星的观测,研究中子星的磁场和吸积流的相互作用

  4. 1. 测量脉冲周期及其演化 Her X-1 Reig et al. 2009 Bildsten et al. 1997

  5. 2. 中子星磁场测量——回旋线 Truemper et al. 1983

  6. 中子星磁场测量观测——螺旋桨效应 • X射线流量的大幅光变可以用来研究X射线脉冲星的螺旋桨效应、估计中子星磁场 GX 1+4 GRO J1744-28 Cui 1997

  7. 3. Integral大质量X射线双星 Obscured HMXBs SFXTs Sidoli 2010 Truemper et al. 2010

  8. 小质量X射线双星 • 研究目标 • 强引力场下物质动力学和辐射性质 • 致密星物态 • 吸积盘物理

  9. 快速光变 4U1728-34 4U1608-52 van der Klis 2006

  10. 2. 长期光变和能谱演化 • 通过测量宽波段谱能够较准确地确定辐射总光度,从而限制不同能谱状态,特别是能够确定现在有争议的硬谱态下吸积流的结构和辐射。

  11. 3. 热核爆发 • 连续谱、振荡、超暴 Strohmayer 2006
