What does the term luminosity mean when referring to stars?

• The color of the star

What is the last stage in life for a low mass or average sized star like our Sun?

• Main Sequence

• White Dwarf

• Planetary nebula

• Black Hole

What is the name of the cloud of dust and gas that will eventually forma high mass star?

Describe the lifespan of a high mass star compared to the lifespan of a low mass or average star such as our Sun.

• Massive stars live longer
