The following text describes four different stars. Using the Hertzsprung-Russell diagram from earlier in the companion, determine whether each star is a giant, supergiant, white dwarf, or main sequence star:
Star 1:Color: Red-orange Surface temperature: 4000 K Luminosity: approximately 100 times dimmer than Earths Sun
Star 2:Color: Yellow Surface temperature: 5100 K Luminosity: approximately 75 times brighter than Earths Sun
Star 3:Color: White Surface temperature: 9000 K Luminosity: more than 10,000 times brighter than Earths SunStar 4:Color: Yellow Surface temperature: 6500 K Luminosity: approximately 1,000 times dimmer than Earths Sun
Where in its life cycle is Star 1?
Where in its life cycle is Star 2?
Where in its life cycle is Star 3?
Where in its life cycle is Star 4?
