The Solar Wind consists of charged particles going out from the Sun. The particles are electrons and protons with a high Kinetic Energy from the high Temperature of the Sun's Corona. 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:
Advanced Composition Explorer (ACE)
Coronal Mass Ejection (CME)
Interplanetary Medium (IPM)
New Horizons (NF1)
Solar and Heliospheric Observatory (SOHO)
