The evolution of 100 M/sub sun/, 150 M/sub sun/, and 2200 M/sub sun/ stars has been studied, with the emphasis placed upon the composition of the material returned to the interstellar medium by the stellar winds. Stars with a mass greater than approx.100 M/sub sun/ can do enough processing via the Na-Ne and Mg-Al cycles to redistribute these nuclei and produce significant amounts of /sup 26/Al. Core helium-burning s-process nuclei also are injected into the interstellar medium. The strong stellar winds provide by a large energy source for locally accelerating cosmic rays, which would modify the composition of the solar nebula by nuclear reactions.
