13. In the same simulation, leave the temperature around the middle and adjust the luminosity back and forth. Where would we find a cooler but very bright star on the diagram?

*1 point

A. Top left
B. Top right
C. Bottom left
D. Middle

D. Middle

To find a cooler but very bright star on the diagram, you would need to adjust the luminosity while leaving the temperature around the middle.

In the Hertzsprung-Russell diagram, temperature typically increases from right to left (hotter stars on the left, cooler stars on the right), and luminosity typically increases from bottom to top (brighter stars towards the top).

Since we want a cooler but very bright star, it means we are looking for a star that is on the right side (cooler) but towards the top (very bright).

Based on this information, the answer is:

B. Top right
