WebStars populate the universe with elements through their “lifecycle”—an ongoing process of formation, burning fuel, and dispersal of material when all the fuel is used up. Different stars take different paths, however, depending on how much matter they contain—their mass. WebDec 7, 2024 · 1. Nebula and Protostar Stage.

Webred dwarf star, also called M dwarf or M-type star, the most numerous type of star in the universe and the smallest type of hydrogen-burning star. Red dwarf stars have masses from about 0.08 to 0.6 times that of the Sun. … WebMar 25, 2024 · white dwarf star, any of a class of faint stars representing the endpoint of the evolution of intermediate- and low-mass stars. White dwarf stars, so called because of the white colour of the first few that were discovered, are characterized by a low luminosity, a mass on the order of that of the Sun, and a radius comparable to that of Earth. Because of … Stellar evolution starts with the gravitational collapse of a giant molecular cloud. Typical giant molecular clouds are roughly 100 light-years (9.5×10 km) across and contain up to 6,000,000 solar masses (1.2×10 kg). As it collapses, a giant molecular cloud breaks into smaller and smaller pieces. In each of these fragments, the collapsing gas releases gravitational potential energy as heat.
