Web8 jan. 2024 · Key Facts & Summary. Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our Sun, stars appear as dots of light in the sky. Each and every one of them is light-years away from us and much brighter than our own star, the Sun. WebFor the production of oxygen, we use the relation between the mass of the He-C-O core at the end of the He or C-burning phase and the yield in oxygen by Arnett ( 1991 ). Taking both the N and O productions for the models at Z = 0.00001 and convoluting them with a standard initial mass function, we get a ratio log . northern lights map 2022Web29 apr. 2016 · Oxygen is the third most abundant element in the universe, after hydrogen and helium.
