48. Disk-jet coupling in Galactic Black Hole transients in the era of SKA

张先 (Shanghai Astronomical Observatory)

Galactic Black Hole (BH) transients show coupling between the generation of jets and the processes of accreting (i.e., disk-jet coupling) around the central engines. During their hard and quiescent states the radio emission from the compact jets are non-linearly correlated to the X-ray emission from the inner accretion flow, which as an observational tool plays an unparalleled role in...

33. Insight-HXMT discovery of the highest energy CRSF from the first Galactic ultra-luminous X-ray pulsar Swift~J0243.6+6124

Measuring the cyclotron resonance scattering feature (CRSF) is the only way to measure directly and reliably the magnetic field near the surface of a neutron star (NS). With the broad energy coverage and large hard X-ray collection area of Insight-HXMT, we have discovered so far the highest energy CRSF up to about 146 keV during the 2017 outburst of the first galactic ultra-luminous X-ray...

50. Insight-HXMT observations on type-I & type-II X-ray bursts

Since the midyead of 2017, Insight-HXMT has observed tens NS X-ray binaries. Among them, hundreds X-ray bursts, including type-I and typ-II bursts, are detected. In a type-I X-ray burst of 4U 1636--536, a shortage at hard X-ray burst is obsersed, which is the first detection in single burst since the privious results are obtined by stacking tens of hundreds bursts of RXTE/INTEGRAL. Also,...

80. On the origin of pulsating ultraluminous X-ray pulsars

侯贤 (云南天文台)

Ultraluminous X-ray sources (ULXs) are off-nucleus objects whose apparent X-ray luminosity exceeds 10^39 erg/s, the Eddington limit of a typical stellar mass black hole (∼10 Msun). Recent studies revealed that some of them are accreting neutron stars (NSs), called pulsating ULXs (PULXs), the luminosity of which is usually more than ∼ 2-3 orders of magnitude higher than most Galactic and nearby...

32. Accretion in X-ray binaries: The geometry and the spectra

乔二林 (NAOC)

X射线双星是恒星级致密天体（恒星级黑洞和中子星）的重要载体，对X射线双星吸积过程的研究对探索恒星级黑洞和中子星周围强引力场中物质的运动规律具有非常重要的意义。在本报告中，我们将在吸积盘蒸发/冕凝聚模型的框架下讨论X射线双星表现出的一些基本观测特征，例如，吸积盘的截断、光谱态转变，以及与光谱态密切相关的相对论喷流的形成与消失等的物理机制。同时,由于中子星存在一个硬的物质表面，而黑洞存在一个视界面，我们将讨论中子星X射线双星由于硬表面的存在而表现出的一些和黑洞X射线双星显著不同的观测现象背后的基本物理过程。最后，我们将简单分析Insight-HXMT时代一些有待进一步探索的关于X射线双星吸积物理的研究内容，以及未来EP和eXTP等对致密天体吸积物理研究的意义。
