If the star is especially massive, when it explodes it forms a black hole. These spin rapidly and can give off streams of radiation, known as pulsars. Dissertation an der Fakultt fur Physik der LudwigMaximiliansUniversitt. After the dust clears, a very dense neutron star is left behind. Despite the influence that high-mass stars have in the evolution of galaxies, being the principal tracers of star formation, the progenitors of core. This material can collect in nebulae and form the next generation of stars. This scatters materials from inside the star across space. After many thousands of millions of years it will stop glowing and become a black dwarf.Ī massive star experiences a much more energetic and violent end. During these changes it will go through the planetary nebula phase, and white dwarf phase. What happens next depends on how massive the star is.Ī smaller star, like the Sun, will gradually cool down and stop glowing. All stars will expand, cool and change colour to become a red giant. The star then enters the final phases of its lifetime. They shape their surroundings by injecting large amounts of energy and momentum and they produce new. Smaller stars use up fuel more slowly so will shine for several billion years.Įventually, the hydrogen which powers the nuclear reactions inside a star begins to run out. Telescope Life Cycle bookmark will model the life cycle of a massive star using beads to represent a stars development. Massive stars play a crucial role in the Universe. This means they may only last a few hundred thousand years. The Sun has one solar mass, and one solar luminosity. Very massive stars use up their fuel quickly. The exact lifetime of a star depends very much on its size. This stage is called the ' main sequence'. Nuclear reactions at the centre (or core) of a star provides energy which makes it shine brightly.
