WebIf stars make up most of the mass of a spiral galaxy, we would expect the galaxies’ masses to increase much more slowly with radius than they actually do. However, spiral galaxy rotation curves indicate that their masses increase directly with radius. WebStars are born with a wide variety of mass. The most massive stars are 100 times more massive than the Sun while the least massive ones are only 0.08 times the mass of the Sun. Most stars spend about 90% of their lifetimes shining due to nuclear fusion that goes on in their cores, but after awhile they evolve and begin to die. litedb browser
