Red Giant Stars.

wildness Giant Stars Red Giants are very large, chill out and luminous whizs. This spot lasts ab show up 10% of the sentiencys life. They are old tips meaning they dont sire much lifespan left. The rubor heavyweight phase occurs in stars, which weigh little than 4 solar masses. The star starts to impart towards the center urinate the star to heat up. The fusion ramble amplifications within the outer(prenominal) shells; this causes the star to expand. The surface cools, making the star turn passing. The red color increases causing the star to more and more expand. Red giants occur as a result of the hydrogen in the core running out. This means that the hydrogen fervent faecal matter only continue in the outer shells well-nigh the atomic number 2 core. The core contracts under gravity until the temperature becomes high large for helium to fuse to carbon copy and oxygen. The helium in the giant star burns for around 10 million years. When the helium runs out it continues burning in the outer shells. The star heats up causing carbon to turn to neon to sodium and and then to magnesium. This lasts close 10 thousand years. Contraction and shell burning continues. neon to oxygen and magnesium lasts 12 years. Oxygen to atomic number 14 and treat lasts 4 years, and silicon to iron takes 1 week.

As a red giant star the sun impulsive lose a lot of mass due to idle gravity at the edge. The outer shells will become top-heavy causing contractions and variability. The star mass is too small for carbon fusion to occur, so the star collapses. The sun will increase its luminosity by 10,000K. It will cool down to 4,000K and expands two hundred radii. Whe n the sun does in conclusion go through the! red giant phase it will end up engulfing mercury, genus Venus and earth. If you want to get a full essay, order it on our website: OrderEssay.net
