麦克斯韦的星团恶魔

The Maxwell's demon of star clusters

Michela Mapelli

摘要:

双星是星团中最重要的能量库。通过三体相遇,双星可以逆转核心坍缩,阻止星团达到均分。此外,双星是形成奇异恒星必不可少的,例如蓝离散星、中等质量黑洞和大质量($\gtrsim{}30$ M $_\odot$)黑洞双星。

英文摘要:

Stellar binaries are the most important energy reservoir of star clusters. Via three-body encounters, binaries can reverse the core collapse and prevent a star cluster from reaching equipartition. Moreover, binaries are essential for the formation of stellar exotica, such as blue straggler stars, intermediate-mass black holes and massive ($\gtrsim{}30$ M$_\odot$) black hole binaries.
