This phenomenon can broaden the P Cygni line profile of objects in its "line-driven" version. This phenomenon's involvement causes a warped magnetic field known as the Parker spiral. This phenomenon can cause a namesake "bubble" in systems like Eta Carina.In some binary systems, this phenomenon can interact with itself to form a pinwheel nebula.

A very strong form of this phenomenon characterizes Wolf-Rayet stars, and occurs when stars exceed the Eddington limit. In the solar system, this phenomenon interacts with a planet's magnetosphere to produce the "bow shock," and the boundary where it slows to sub-sonic speeds is known as the termination shock. For 10 points, name this phenomenon, a plasma stream ejected from stars.
