Web11 jun. 2024 · Red dwarf stars are very-low-mass stars. Because of this, they have low pressures, low fusion rates, and low temperatures. The energy generated is the product of a nuclear fusion of hydrogen into helium by way of photon-proton chain mechanisms. Red dwarf stars are very dim, even the largest of them have only around 10% of the Sun’s … WebThe planetary nebula phase is a final stage in a low- mass star's life. During this phase, the star sheds its outer layers. This creates an expanding, glowing shell of very hot gas. Despite the name, they have nothing to do with planets. They got this name because astronomers using small telescopes long ago, thought they looked a bit like planets.
