To determine the spectral class of a star, the necessary piece of spectral data is temperature.
The spectral class of a star is closely related to its temperature, as it affects the star's color and spectral characteristics.
Use the diagram to answer the question.
The Hertzsprung-Russell Diagram shows the spectral class of stars across the top, the temperature in Kellvin of stars across the bottom. The luminosity of stars, with the luminosity of the Sun equal to one, on the right, and the absolute magnitude of stars on the right. Blue giants, red supergiants, red giants, main sequence stars, the Sun, and white dwarfs are shown on the diagram.
