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 … 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 … WebThe first giant phase is brought on by hydrogen shell fusion while a star is on its way to becoming hot enough to fuse He in it's core. The lowest mass stars do not have enough … 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. the pursuit of scrappiness

WebJan 26, 2024 · Once they run out of their hydrogen fuel, the cores compress and the star expands to become a red giant. It heats up the core until helium fuses to create carbon. When the helium runs out, then the carbon starts to fuse to create heavier elements.
