P9: Space Physics

• PROTOSTAR


  Stars each bigger than the Sun
• MAIN SEQUENCE STAR

  Stars each bigger than the Sun
• RED SUPER GIANT

  Stars each bigger than the Sun
• CLOUD OF DUST AND GAS

  The fly ple the dust and gas fogether to form a gedoe
• The Life Cycle of Stars

  1. The temperature.kes as the star gets dancer and more portices su with each ofer

  2. When the bumpatues gets high oh, bud undergo Ask p.49) to form belum.nuclei

  3. This gives out bag amounts of which keepe the care of the star bat

  4. A star to ben
• MAIN SEQUENCE

  The star enters a stable period where the baceous (p.58) ed by the nuclear fusion that tries to expand the s balances the foron of gay pulling everything ite
• RED GIANT

  • Evendusly the budengan bagina to run out
  • The star than a into a cad and (if it is a small star) or a cedauger get (if it is a larger char)
  • It becomes cd because the surface coal Fusion of helum (and other elements) occurs
  • Ha elements (toon) are created in the g of the star
• WHITE DWARF

  • A small-to-medium-sized star like the Bun then become unchable and lets Wouter layer of dust and 45
  • This leaves behind a hot, dense cold core
• BLACK DWARF


  • As a white dwarf cools do emits less and less energ
  • When it no longer emits significant amount, it is called a black deaf
• Stars undergo more fusion and expand and contract several fiss, forming elements as heavy as leon in various puclear actions


  1. Eventually they explode in a supemova, forming elements beavier than iron and ejecting them into the universe to form new planets and stars

  2. Stars and their life cycles produce and distribute all naturally occurring elements
• SUPERNOVA

  • The aploding pemove throws the outer layers of dust and as into space, leaving very dense core called neutron star
  • If the star is massive enough, it will become a black hole-a super dense point in space that not even light can escape from
• It's the beginning of the world as we know it...
• Pretty neat, seeing how stars like our Sun-which all of us rely on-were made all those years
