Question

thursday 9-11 how does the temperature and luminosity of star b compare to star d?

Explanation:

Step1: Analyze Temperature

Star B is in the White Dwarfs region with a temperature around 20,000 - 40,000 K. Star D is in the Red Supergiants region with a temperature around 2,500 - 5,000 K. So Star B has a higher temperature than Star D.

Step2: Analyze Luminosity

Luminosity on the graph is on a logarithmic scale ( \(10^{-4}\), \(10^{-2}\), 1, \(10^{2}\), \(10^{4}\), \(10^{6}\) ). Star B is near \(10^{-2}\) to \(10^{-4}\) range, Star D is near \(10^{6}\) range. So Star D has a higher luminosity than Star B.

Answer:

Star B has a higher temperature than Star D, but Star D has a higher luminosity than Star B.
