This plasma flow is what causes comet tails to face away from the Sun.
Hydrodynamic interactions due to this phenomenon create Parker spirals, which are a consequence of rotations of the source of this phenomenon. A strong "radiation driven" phenomenon analogous to this is observed in Wolf-Rayet stars and more generally beyond the Eddington limit in other systems. In conjuction with Earth's magnetic field, this is responsible for ‘fueling' the Van Allen Belts. The termination shock is the point where this reaches subsonic speeds, and the heliopause is where it merges with interstellar medium. This plasma flow is what causes comet tails to face away from the Sun. For 10 points, identify this stream of charged particles released from the outer atmosphere of the Sun.
