论文摘要
巨大的恒星驱动强风，影响周围的星际介质，从而为孤立的恒星和年轻簇周围的超级泡沫产生parsec尺寸的气泡。这些气泡可以在整个电磁频谱上观察到风本身和扫荡的星际气体。失控的巨星产生弓形冲击，可强烈压缩星际气体，产生明亮的红外，光学和无线电星云。通过检测到弓冲击的非热射射发射，现在也可以研究颗粒加速度。我回顾了有关大量恒星周围风气泡和弓形冲击的研究，强调了红外线，无线电和X射线观察的最新进展以及这些星云的多维模拟的进展。这些进步能够在理论和观察结果之间进行定量比较，并允许测试某些物理过程的重要性，例如热传导和开尔文 - 霍尔莫尔兹不稳定性在塑造星云中的不稳定性，并限制了恒星反馈的能量学对星际介质的能量。
Massive stars drive strong winds that impact the surrounding interstellar medium, producing parsec-scale bubbles for isolated stars and superbubbles around young clusters. These bubbles can be observed across the electromagnetic spectrum, both the wind itself and the swept up interstellar gas. Runaway massive stars produce bow shocks that strongly compresses interstellar gas, producing bright infrared, optical and radio nebulae. With the detection of non-thermal radio emission from bow shocks, particle acceleration can now also be investigated. I review research on wind bubbles and bow shocks around massive stars, highlighting recent advances in infrared, radio and X-ray observations, and progress in multidimensional simulations of these nebulae. These advances enable quantitative comparisons between theory and observations and allow to test the importance of some physical processes such as thermal conduction and Kelvin-Helmholtz instability in shaping nebulae and in constraining the energetics of stellar-wind feedback to the interstellar medium.
