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 ...

When a star of less than about 8 solar masses runs out of hydrogen in its core, the mainly helium core collapses and heats up. When it gets hot enough fusion reactions start in the layer of hydrogen surrounding the core. This causes the outer layers of the star to expand into a …
WebMay 7, 2015 · It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the … WebOct 31, 2024 · How a red giant evolves will be largely dependent upon its mass.

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

Eventually, the red giant … cincinnati ohio to new orleansWebAgain, 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. dhs publication 1010WebRed giant.
