  32. MAIN SEQUENCE STAR is:

  33. MAIN SEQUENCE STAR is: A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into energy. It is then usually called a dwarf star. This is the longest period in a stars lifetime.

  47. Luminosity is:

  48. Luminosity is: a measure of the radiant power emitted by a star.

  49. Hertzsprung-Russell diagram is:

  50. Hertzsprung-Russell diagram is: a scatter graph of stars in which the absolute magnitude (intrinsic luminosity) of stars is plotted vertically against their surface temperature (or corresponding spectral types)
