For a standard H-R diagram, what are the stars in the lower left region of the diagram?

• Main sequence stars

• Supergiants

• Giants

• White dwarfs

How do white dwarfs compare with supergiants, in terms of temperature and luminosity?

• White dwarfs are cooler and have higher luminosity than supergiants.

• White dwarfs are cooler and have lower luminosity than supergiants

• White dwarfs are warmer and have higher luminosity than supergiants.

• White dwarfs are warmer and have lower luminosity than supergiants

Looking at the Atomic Spectra of different stars, one can determine what elements were present in the stars through the light they emitted. One observation was that some stars did NOT contain metals. What would this observation suggest?

• Metals in Stars must be blocking the light from escaping

• The stars were not hot enough to melt metals

• These stars did not have metals when they formed

• These stars were not massive enough to produce metals
