  In star: Stellar activity and mass loss
  …types are active and have stellar winds analogous to the solar wind. The importance and ubiquity of strong stellar winds became apparent only through advances in spaceborne ultraviolet and X-ray astronomy as well as in radio and infrared surface-based astronomy.

  In meteorite: Meteorites and the formation of the early solar system
  …AGB stars produce massive fast-moving winds (flows of matter) that are rich in short-lived radionuclides. Numerical simulations show that under some conditions, when these winds hit an interstellar molecular cloud that cannot collapse spontaneously, they compress it to the point that it becomes gravitationally unstable and collapses. The simulations also…

  In H II region
  …gas also arises from the stellar winds of the exciting stars. These winds create a large cavity or bubble in the denser, cooler gas originally surrounding such a star. In the interior of the bubble, the radially flowing stellar wind passes through a transition in which its radial motion is…
