Superbubbles

Abstract

Superbubbles were defined and explained in this chapter. Examples were given, including Cygnus OB 1, the Aquila supershell, the Monogem Ring, NGC 1929 and Orion-Eridanus. It was documented that superbubbles generate and disseminate radiation. Explosions were also associated with superbubbles. Superbubbles produce both termination shock and secondary shocks. Plasma waves are created by superbubbles, it was demonstrated. The inherently turbulent and chaotic inner nature of superbubbles was documented.
