How much mass does a star have
WebMar 22, 2015 · The mass ejected in the supernova is the difference between the curve marked remnant mass, which specifies (for these models) how much matter became part of the remnant, and the final mass, which was the mass of the star at collapse, after it had already lost a lot during its life. The interesting point in this prediction is the change … WebJul 15, 2014 · Average stars with up to 1.44 solar masses, such as the Sun, face only a slightly less exotic fate. As they run out of hydrogen to fuse in their cores, they swell into red giant stars before shedding their outer layers. The remnant left behind in these planetary nebulae is a white dwarf star.
