WebThe way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant.

WebGiants and supergiants form when a star runs out of hydrogen and begins burning helium. As the star’s core collapses and gets hotter, the resulting heat subsequently causes the … WebDuring the main sequence, the star is supported by the fusion of hydrogen into helium. Eventually, the hydrogen runs out at the centre, so hydrogen fusion is no longer possible there. Why doesn't it start fusing helium into carbon right away?

WebWhen a main sequence star runs out of hydrogen fuel in its core, fusion stops. The outward radiation pressure the keeps the star from collapsing is now gone, and gravity causes the star to start to collapse. The collapse of the core causes the temperatures to increase in … WebWhen stars have exhausted all their hydrogen fuel, they evolve to red giants. Their outer layers of gas expand and cool; therefore, the stars move to the right on the H-R diagram. Although a star cools when it becomes a red giant, it grows so large its luminosity (or total power emitted) increases. Therefore, the star also moves up the H-R diagram.

A star becomes a giant after all the hydrogen available for fusion at its core has been depleted and, as a result, leaves the main sequence. The behaviour of a post-main-sequence star depends largely on its mass. For a star with a mass above about 0.25 solar masses (M☉), once the core is depleted of hydrogen it contracts and heats up so that hydrogen starts to fuse i… WebChapter 10 1.
