Compare life histories of a meduim size star and a giant star. How are they similiar?How are they different? - different meduim hairstyles
A star of modest size can be like our star, the sun. Once enough material, particularly in the form of hydrogen has been accumulated by the merger within the gravity of the star begins to be converted from hydrogen and helium. This amounts to about 10 billion years ago, when the star expands into a red giant and then decrease over time into a white dwarf.
A huge star has a lifetime much shorter, perhaps only one million years, when the star into a supernova and then collapse into a black hole.
