银河系X射线双星喷流

Galactic X-ray binary jets

Elena Gallo

摘要:

银河系X射线双星具有相对较快的变化时间尺度,为探索不同区域的吸积物理和相关现象(最显著的是外流)提供了一个极好的实验室。在比较了黑洞X射线双星系统和中子星的喷流现象之后,本文讨论了喷流在很低的爱丁顿比下的作用,并给出了用“最大喷流主导”模型拟合静止黑洞双星的宽带谱能量分布所得到的初步结果。

英文摘要:

With their relatively fast variability time-scales, Galactic X-ray binaries provide an excellent laboratory to explore the physics of accretion and related phenomena, most notably outflows, over different regimes. After comparing the phenomenology of jets in black hole X-ray binary systems to that of neutron stars, here I discuss the role of the jet at very low Eddington ratios, and present preliminary results obtained by fitting the broadband spectral energy distribution of a quiescent black hole binary with a `maximally jet-dominated' model.
