WebCarbon and oxygen fuse to form neon, then magnesium, then silicon. All forming into burning shells surrounding an iron ash core. Iron is unusual in that it is extremely stable and resistant to fusion. The temperature of an iron core can reach 3 billion degrees. 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.

WebPlanets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star's wind blows away their gases and because they are made of heavier materials attracted by the star's gravity. Why Do Red Giants Expand? Watch on WebIn the Hayashi limit, stars above this radius would be too unstable and simply do not form. Red supergiants have masses between about 10 M ☉ and 30 or 40 M ☉. Main-sequence stars more massive than about 40 M ☉ do not expand and cool to become red supergiants. Red supergiants at the upper end of the possible mass and luminosity range are ... WebThe change in temperature causes the star to glow redder. The star is now a red giant. Red giants can be 20 and 100 times that of the Sun though only contain 0.25 to 8 times the mass of the Sun.
