Explanation:

Stars live for millions and even billions of years. The larger the star, the faster it ages, the faster it burns the fuel, but no matter what, the life span of the star is very long. The thermonuclear reactions last until the hydrogen in the star is depleted, that is, until iron, the most stable element in the universe, is formed, because then there is nothing else to convert. Of course, the formation of iron occurs after a series of transformations, because from hydrogen, helium is produced, then carbon, nitrogen, oxygen and so on until iron. The biggest stars live the shortest because they are rapidly consuming their nuclear fuel, ie. hydrogen. Other stars, such as the sun, are slower to consume fuel and live for about 10 billion years. In most cases, the size of a star indicates its age. The smallest stars are the youngest, and the larger ones are nearing their end, either cooling or supernova explosion.The white dwarf is small and dense, the neutron star smaller and denser. White dwarfs rotate rapidly and often have strong magnetic fields, and neutron stars rotate even faster and have even stronger magnetic fields. The dimensions of the white dwarf are about 10,000 km in diameter, while the typical neutron star is only 30 km in diameter. The pressure in a neutron star is huge. It contains so much matter in such a small volume that only one teaspoon of neutron star material would weigh 40 billion tons.
