Isn't it fascinating that scientists can make statements about this star like these??!! "The sun has been around for about 4½ billion years, but this star has been glowing for about 13 billion!!" and

"Caffau's star" shouldn't exist at all. It's very deficient in two elements — carbon and iron — that many theorists believe are critical components for normal stars to form. It's also deficient in lithium, which is not essential for a star to take shape but ought to be present all the same

"Most stars are composed of around 70 percent hydrogen and 28 percent helium by mass, very similar to what we see in the Sun."  (source:http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/961112a.html ) To learn more about the chemical composition please read the article, "The Chemical Composition of Stars and the Universe" written by  Michael Richmond by clicking on the following link: http://spiff.rit.edu/classes/phys240/lectures/elements/elements.html
