WebMay 7, 2015 · The star has become a red giant. What happens next in the life of a star depends on its initial mass. Whether it was a "massive" star (some 5 or more times the mass of our Sun) or whether it was a "low or medium mass" star (about 0.4 to 3.4 times the mass of our Sun), the next steps after the red giant phase are very, very different. III. The End WebThe stars that become red giants are those that have used up their nuclear fuel and are now burning helium; this process is called “helium flash.”.

WebIt has entered its second red giant phase. What happens next depends on the mass of the star. Low-mass, Sun-like stars enter the planetary nebula stage. Stars which contain more than 8 times the mass of the Sun are … WebSince the fusion occurs as a “shell” around the stellar core, the outward-push from the fusion is what pushes the star’s outer layers further. The result is that the star grows into a Red Giant. My question is this: Why does fusion cease in the core?! the pack dayna lorentz

WebAug 14, 2024 · The Sun is said to become a red giant at the end of its life (before that it will become an orange subgiant first and then an orange giant or so) and after ejecting its outer layers it should become a white dwarf. If yellow dwarfs like the Sun become red giants, what do red dwarfs become? Even redder giants? WebPlanetary nebulae seem to mark the transition of a medium mass star from red giant to white dwarf. Stars that are comparable in mass to our Sun will become white dwarfs within 75,000 years of blowing off their envelopes. Eventually they, like our Sun, will cool down, radiating heat into space and fading into black lumps of carbon.

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, the collapsing core may become hot enough to support more exotic nuclear reactions that consume helium and produce a variety of heavier elements up to iron.

WebThe star will continue to expand to between 200-800 times the radius of our sun to become a red giant. Stars larger than our sun will increase in size to form a Red Supergiant star. It will expand to about 1500 times the radius of our sun. Both red giants and red supergiants decrease in surface temperature down to around 3500 Kelvin. WebLike the Sun, all G-type stars convert hydrogen into helium in their cores, and will evolve into red giants as their supply of hydrogen fuel is depleted. Orange Dwarfs Orange dwarf stars …
