Abstract

The Insight Hard X-ray Modulation Telescope (Insight-HXMT) satellite has achieved a series of significant scientific breakthroughs during its on-orbit operation, thanks to its unique broadband coverage (1–250 keV) and large effective area. By monitoring the outburst evolution of numerous black hole X-ray binaries (BHXBs), Insight-HXMT has provided crucial observational data for investigating accretion processes during these events. These outbursts include not only typical complete outbursts, which progress through hard, intermediate, and soft states, but also “failed transition outbursts”, where the system remains in the hard or intermediate states without fully transitioning. The broadband capabilities of Insight-HXMT offer a valuable opportunity to gain deeper insights into the properties of the accretion disc, corona, and jet in BHXBs. Furthermore, these observations play a crucial role in advancing our understanding of BHXBs outburst mechanisms and accretion radiation physics. This article focuses on the evolution and characteristics of BHXBs outbursts as revealed by Insight-HXMT data.

用Insight-HXMT研究黑洞x射线双星的爆发演化

洞察号硬x射线调制望远镜（Insight- hxmt）卫星凭借其独特的宽带覆盖（1-250 keV）和大有效面积，在其在轨运行中取得了一系列重大科学突破。通过监测众多黑洞x射线双星（BHXBs）的爆发演化，Insight-HXMT为研究这些事件中的吸积过程提供了重要的观测数据。这些爆发不仅包括典型的完全爆发（经历硬、中间和软状态），还包括“失败的过渡爆发”（系统在没有完全过渡的情况下保持在硬或中间状态）。Insight-HXMT的宽带功能为深入了解bhxb中吸积盘、日冕和喷流的特性提供了宝贵的机会。此外，这些观测结果对推进我们对BHXBs爆发机制和吸积辐射物理的理解起着至关重要的作用。本文重点介绍Insight-HXMT数据揭示的BHXBs爆发的演变和特征。

期刊介绍： The vigorous growth of astronomical and astrophysical science in China led to an increase in papers on astrophysics which Acta Astronomica Sinica could no longer absorb. Translations of papers from two new journals the Chinese Journal of Space Science and Acta Astrophysica Sinica are added to the translation of Acta Astronomica Sinica to form the new journal Chinese Astronomy and Astrophysics. Chinese Astronomy and Astrophysics brings English translations of notable articles to astronomers and astrophysicists outside China.
