X射线双星爆发和演化的系统观测研究

硬X射线调制望远镜(即“慧眼”)卫星的发射标志着我国天文界同事可以使用我国的X射线空间天文卫星针对黑洞和中子星等致密天体开展X射线观测研究。基于过去多年来我们在黑洞和中子星X射线双星领域打下的研究基础，我们将通过"慧眼”卫星对暂现黑洞和中子星双星爆发和持续对象长期演化的高频次观测和扫描观测，结合国际上X射线全天监视器以及其他空间和地面观测设备的观测，研究黑洞和中子星暂现双星爆发的早期发现和预警、X射线时变、能谱和喷流特征和整体演化、X射线谱态特征和谱态跃迁、吸积和喷流间的耦合等观测课题，揭示小质量X射线双星暂现源的爆发机制、建立X射线双星谱态跃迁的物理图像、发现吸积和喷流的耦合机制、探测和研究广义相对论效应并限制中子星质量-半径关系等。

The launch of the HXMT marks the era of the availability of X-ray satellite entirely accessible to the Chinese community to study black holes and neutron stars. Based on past research on black hole and neutron star X-ray binaries, we intend to make use of HXMT observations, by either pointings or scans, as well as other X-ray monitors and space or ground facilities, to study the outbursts of transient black holes and neutron stars, X-ray timing and spectral properties, radio jet evolution, including spectral state transitions and the coupling between accretion and jet in X-ray binaries. The goal of the project is to reveal the mechanisms of the outbursts of low mass X-ray binary transients, build up physical picture of spectral state transitions, discover the link between accretion and jet, and probe general relativistic effects and constrain neutron star mass-radius relation, etc.
