Web18 de jun. de 2008 · Emission Nebulae: A Star Is Born. When a protostar becomes a self-radiating object, fueled by its own thermonuclear reactions, it becomes a true star. If it's massive enough, a star can ionize the nebular material, producing an area of fluorescence around it. The dark nebula, now glowing, becomes an emission nebula. WebStars less than about 10 times the mass of the Sun become asymptotic-giant branch stars – red giants with inert, degenerate carbon/oxygen cores, that fuse helium in the shell around the core. This helium fusion causes the star to become unstable and the envelope is ejected as a planetary nebula.
