Efficiently Cooled Stellar Wind Bubbles in Turbulent Clouds. I. Fractal Theory and Application to Star-forming Clouds

L Lancaster, EC Ostriker, JG Kim… - The Astrophysical …, 2021‏ - iopscience.iop.org
Winds from massive stars have velocities of 1000 km s− 1 or more and produce hot, high-
pressure gas when they shock. We develop a theory for the evolution of bubbles driven by …
