Exam points

  • Describe the high-mass star sequence from nebula and protostar through main sequence and red supergiant to supernova and a neutron star or black hole.
  • After the main sequence, give the sequence red supergiant → supernova → neutron star or black hole.
  • Use stellar mass to distinguish stars that become red supergiants and supernovae from Sun-like stars that become red giants.
