How do stars turn into red giants
In approximately five billion years, our own sun will transition to the red giant phase. When it expands, its outer layers will consume Mercury and Venus and also reach Earth. Scientists are still debating whether or not our planet will be engulfed, or whether it will orbit dangerously close to the red giant sun. Either … See more Most of the stars in the universe are main sequence stars — those that convert hydrogen into helium in their cores via nuclear fusion. Over … See more In recent years, astronomers have gotten some good looks at a few relatively nearby red giants, learning more about how these behemoths operate.

WebThe increasingly hot core also pushes the outer layers of the star outward, causing them to expand and cool, transforming the star into a red giant. If the star is sufficiently massive, … WebFrom Main-Sequence Star to Red Giant Eventually, all the hydrogen in a star’s core, where it is hot enough for fusion reactions, is used up. The core then contains only helium, “contaminated” by whatever small percentage of heavier elements the star had to begin with.

Inside a star, hydrogen atoms are combined together to form helium atoms. This process creates the energy that the star needs to resist the force of gravity that is trying to crush the star together, and also causes the star to light up.

WebFor a star to transition to a red giant, it must possess a mass between one-half to eight times the mass of our Sun; astronomers term these stars low or intermediate mass. Nuclear fusion is the process by which two atoms combine to form a larger one. This process occurs in a star’s core, where hydrogen atoms are combined to form helium.
