摘要:

恒星质量黑洞周围的吸积盘为研究标准薄盘、超爱丁顿盘以及可能与通量变化有关的结构的基础物理提供了独特的机会。这些活动星系核(AGN)的局部类似物因其接近性、高通量和X射线波段的峰值发射率而特别有吸引力。能量分辨率为2-5 eV的X射线量能谱仪非常适合研究恒星质量黑洞中的吸积。这些结果将对适用于广泛环境的种子盘理论进行强有力的测试,有助于推动新的数值模拟,并将为我们对AGN燃料,演化和反馈的理解提供信息。

英文摘要:

Accretion disks around stellar-mass black holes offer unique opportunities to study the fundamental physics of standard thin disks, super-Eddington disks, and structure that may be connected to flux variability. These local analogues of active galactic nuclei (AGN) are particularly attractive for their proximity, high flux, and peak emissivity in the X-ray band. X-ray calorimeter spectrometers, with energy resolutions of 2-5 eV, are ideally suited to study accretion in stellar-mass black holes. The results will make strong tests of seminal disk theory that applies in a broad range of circumstances, help to drive new numerical simulations, and will inform our understanding of AGN fueling, evolution, and feedback.
