I was wondering what the types of stars were? I
only know a few, such as white dwarf, and red giant.
About 90 percent of the stars lie in the H-R diagram, marked by the main
A star shines by radiating energy from the nuclear reactions. Once a
star runs out of its fuel, it dies and becomes compact. The lifetime of a
star depends on its mass. High-mass stars evolve faster and die sooner
than low-mass stars. The most massive stars may live only a few million
years, and the lowest mass stars can live 100's of billions of years.
Low-mass stars die quietly, while high-mass stars die in tremendous
explosions (supernovae explosions). A star like our Sun would die and end
as a white dwarf:
Stars about five to ten times more massive than our Sun would explode and
form a neutron star. More massive stars turn into black holes:
