WebThe main sequence is thus explained as the group of stars of different masses that have reached stable configurations and are generating energy by consuming hydrogen in nuclear reactions. Mathematically, a star's luminosity is proportional to the mass to the 3.5 power. In solar units, L = M 3.5. WebHowever, neutron stars (like white dwarfs) have a maximum mass near 3 M Sun, over which neutron degeneracy pressure can't balance gravity. In the very high mass stars, the neutron star goes over the critical mass, and … dacia stepway automatic
