(11)  Science concepts. The student knows the characteristics and life cycle of stars. The student is expected to:

  • (A)  identify the characteristics of main sequence stars, including surface temperature, age, relative size, and composition;
  • (B)  characterize star formation in stellar nurseries from giant molecular clouds, to protostars, to the development of main sequence stars;
  • (C)  evaluate the relationship between mass and fusion on the dying process and properties of stars;
  • (D)  differentiate among the end states of stars, including white dwarfs, neutron stars, and black holes;
  • (E)  compare how the mass and gravity of a main sequence star will determine its end state as a white dwarf, neutron star, or black hole;
  • (F)  relate the use of spectroscopy in obtaining physical data on celestial objects such as temperature, chemical composition, and relative motion; and
  • (G)  use the Hertzsprung-Russell diagram to plot and examine the life cycle of stars from birth to death.
