solar wind

(charged particles emanating from the Sun)

The solar wind consists of charged particles traveling out from the Sun. The particles are electrons and protons with a high kinetic energy from the high temperature of the Sun's corona, i.e., they consist of the high-speed tail of the corona's Maxwell-Boltzmann distribution that exceeds the Sun's escape velocity. The solar wind eventually hits the interstellar medium, carving out a bubble around the solar system called the heliosphere.

Stars can discharge similar stellar winds, of charged or neutral particles. Rates vary up to 2000 km/s. Examples:
