Respuesta :

Temperature - Star characteristics that determines color.

Giant - Medium mass stars at the end of the life cycle.

White Dwarf - Current category of the sun.

Super Giant - Low temperature, high luminosity stars.

Main sequence - Small dim stars that remain after nuclear fusion.

Explanation:

  • The surface temperature of the star determines the color of the star. The wavelength of the light emitted by the star is based on its surface temperature. For example, The sun appears blue in color, if it is hot and appears in red if it is cold.
  • Giant appears as small bodies as compared to the super giant which has a medium mass at the end of the life cycle.
  • The white dwarf was invented first as white and then discovered to be blue. They currently belong to the sun's category, where the sun is known as a yellow dwarf.
  • Super Giant can be seen in the upper right of the H-R diagram which clearly shows the red color due to low temperature. whereas, the large mass of super giant gives high luminosity.
  • The main sequence is a fusion of hydrogen into helium. After nuclear fusion, they remain small and dim which is represented in the lower right side as Red color balls.

Answer:   It is fusing hydrogen at its core. -- Vega

It has lost its outer shell and retained only a hot core that is slowly losing its brightness. -- Procyon B

Its temperature has decreased, but it is shining brighter than before.-- Polaris

Explanation:  I just took the test and this is correct
