Q

Lifecycle of a fucking star

A
  • Cloud of gas (nebula)
  • Gravity pulls them together and the cloud becomes more concentrated
  • Temperature of the cloud increases
  • Eventually temperatures are so high and pressures are so great that the particles fuse together
  • Fusion occurs as the lighter nuclei fuse to form helium
    hydrogoen
  • Creatiga large amount ogf energy
  • This release of energy opppses the collapse of the cloud due to gravity
  • Eventually an equilibrium forms where the force of gravity and the energy released from fusion balance
  • Thuis, a star has formed
  • EVentually the star runs out of helium to fuse
  • So it is not in equilibrium
  • The star collapses
  • If massive, the star collapses, increasing the pressure and temoerature of core
  • Heavier nuclei fuse
  • Red supergiant
  • Once all the elements up to iron have been fused, it forms a supernova
  • Which is followed by either a black hole or a neutron star
  • If the star is normal sized, it forms a red giant
  • White dwarf
  • Black dwarf
