How do red giants form

WebApr 13, 2024 · When a red supergiant has burnt out most of its fuel it resulst in a gravitational collaps, lowering its volume making the star smaller. When it shrinks the temperature get higher resulting in the start of thermonuclear fusion emiting great force and a giant explosion in the form of a supernova. Answer link WebAccording to Wikipedia, the red giant phase begins when the Hydrogen in the stars center is completely converted to Helium. Hydrogen is then fused to Helium in a shell surrounding the inert Helium core. This occurs a few thousand times faster than the earlier phase, so its lifetime is a few thousand times less than the main sequence phase that ...

A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M☉)) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower. The appearance of the red giant is … See more A red giant is a star that has exhausted the supply of hydrogen in its core and has begun thermonuclear fusion of hydrogen in a shell surrounding the core. They have radii tens to hundreds of times larger than that of the See more Red giants with known planets: the M-type HD 208527, HD 220074 and, as of February 2014, a few tens of known K-giants including See more The Sun will exit the main sequence in approximately 5 billion years and start to turn into a red giant.

WebMay 7, 2015 · Stars larger than eight times the mass of our Sun begin their lives the same way smaller stars do: by fusing hydrogen into helium. However, a large star burns hotter and faster, fusing all the hydrogen in its core to helium in less than 1 billion years. The star then becomes a red supergiant, similar to a red giant, only larger. Unlike red ... WebFusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of …

WebA red giant forms after a star has run out of hydrogen fuel for nuclear fusion, and has begun the process of dying. A star maintains its stability through a fine balance between its own … WebRed giant As medium sized stars exhaust their hydrogen content, they expand up to 100 times their original size to become red giants. The nuclear fusion reactions occurring within a red giant are H→ He and He→ C. Our Sun will follow this path over the next 5 billion years. This red giant is Aldebaran in the constellation Taurus.

http://abyss.uoregon.edu/~js/ast122/lectures/lec16.html WebAgain, a red supergiant forms when the hydrogen supply runs out in the core of a massive star. During this time, the star begins to fuse heavier and heavier elements. The process ceases when the star begins to fuse iron because this requires more energy than it generates. Most super red giants will explode as Type II supernovae when this happens.

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 ...
