contents Stellar winds form an integral part of astronomy. The solar wind affects Earth's magnetosphere, while the winds of hot massive stars are highly relevant for galactic feedback through their mechanical wind energy. In different parts of the stellar HR diagram different forces dominate. On the hot side of the HRD radiative forces on ionised gas particles are active, while on the cool side molecular and dust opacities take over. Moreover, due to the convective envelopes, alternative physical ingredients may start to dominate. I will describe the basic equation of motion and give a few examples, mostly focusing on the winds from massive stars. Here mass-loss rates significantly affect the stellar evolution all the way to core collapse as a supernova and/or black hole formation event.
