Stellar Wind

The sun emits a constant stream of particles, mostly protons and electrons, that are known as the solar wind. Many stars also have a similar phenomenon, known as stellar wind. The solar wind is fairly gentle. Stellar winds as gentle as the solar wind are difficult to detect from the earth because other stars are so distant. However, many stars at certain stages in their evolution have very strong stellar winds. These strong winds produce effects that we can observe from Earth. They also can cause the star to lose significant amounts of mass.

Analogous to the solar wind many stars have stellar winds. Because stars are so distant, stellar winds that are as gentle as the solar wind do not produce dramatic effects as seen from the earth. The stellar winds that we observe are therefore much stronger than the solar wind. A variety of different types of stars display interesting stellar winds.
