  • [FREE] What is the final stage of a star with a mass much greater than . . .
    The final stage of a star with a mass much greater than that of the Sun is either a neutron star or a black hole, depending on the mass of the core left after a supernova explosion Massive stars expand into red giants and undergo core collapse, leading to these two outcomes
  • The Life Cycles of Stars - Imagine the Universe!
    A White Black Dwarfs A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel Near the end of its nuclear burning stage, such a star expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf
  • The life cycle of a star - AQA The formation and life cycle of stars - BBC
    Stars that are far greater in mass than the Sun follow the right hand path: supernovaThe large explosion at the end of a large star’s life, which distributes much of the elements formed in the

  • The Stages of the Life Cycle of a Star – A Cosmic Evolution
    For example, a low-mass star like our Sun will spend about 10 billion years in the main sequence, while a more massive star may only last a few million years The red giant and supergiant phases are relatively short, typically lasting a few million years or less The final stages—white dwarfs, neutron stars, and black holes—can persist for
  • Life Cycle of Stars Flashcards - Quizlet
    Place the following stages in the life of a low-mass star, like the sun, in order: A) Red giant; B) White dwarf; C) Main sequence star
  • What is the final state of a medium-mass star (Sun-like)?
    Overall, the final state of a sun-like medium-mass star is a white dwarf, which is significantly smaller and denser than its previous phases An example would be the star Betelgeuse, which is currently in the red supergiant stage and may one day become a white dwarf after exploding as a supernova
  • Star - End States, Fusion, Evolution | Britannica
    The final stage of this kind of low-mass star is typically a ball not much larger than Earth but with a density perhaps 50,000 times that of water The Sun is destined to perish as a white dwarf But, before that happens, it will evolve into a red giant, engulfing Mercury and Venus in the process
