Question

i. Look at the list of stars on the first page of this lab, and identify at least one star that fits into each of the above 5 categories. The 5 categories are main sequence, red giants, red supergiants, red dwarfs, and white dwarfs. First is a list of the 15 most nearby stars in the sky. Luminosities are given relative to the sun (how much brighter or fainter the star would appear if located right next to the sun) and temperatures in degrees Celsius.
