How to Move Ionized Gas: An Introduction to the Dynamics of HII Regions

  • W.J. Henney
Part of the Astrophysics and Space Science Proceedings book series (ASSSP)

Abstract

HII regions are volumes of gas surrounding high-mass stars that are ionized and heated by the stellar ultraviolet radiation. This ionization and heating significantly raises the thermal pressure of the gas, which is the principal driver of the dynamics of all but the very smallest and very largest HII regions.
