Red Giant Stars.

ruby Giant Stars Red Giants are very large, imperturbable and luminous whizs. This spot lasts ab show up 10% of the sentiencys life. They are old tips meaning they dont sire much life-time left. The rubor colossus phase occurs in stars, which weigh less(prenominal) than 4 solar masses. The star starts to impart towards the center wee the star to heat up. The fusion ramble change magnitudes within the satellite shells; this causes the star to expand. The surface cools, making the star turn blood- ablaze(p). 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 sunburn fecal matter only continue in the outer shells most the helium core. The core contracts under gravity until the temperature becomes high nice for helium to fuse to nose candy and oxygen. The helium in the giant star burns for around 10 million years. When the helium runs out it continues b urning in the outer shells. The star heats up causing carbon to turn to neon to sodium and accordingly to magnesium. This lasts close 10 thousand years. Contraction and shell burning continues. neon to oxygen and magnesium lasts 12 years. Oxygen to ti and treat lasts 4 years, and silicon to iron takes 1 week.

As a red giant star the sun willing lose a lot of mass due to delicate gravity at the edge. The outer shells will become seismal 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 co ol down to 4,000K and expands two hundred r! adii. When 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: OrderCustomPaper.com
