Question

Part 1: Describe the mass and surface temperature of the supergiant stars. Part 2: Explain where on the HR diagram you would expect to find a supergiant star based on its physical properties.

Answer 1

Supergiants have a low surface temperature and are brighter than any other stars. They are so bright because they are the largest stars in the universe.

On the HR diagram, you will find Supergiants in the top right corner, with an absolute brightness of 6 and a surface temperature between 2,500 to 5,000.

Step-by-step explanation:

Answer 2

Hello!

The biggest type of stars in the universe are blue super giant stars. They can have up to 20 times bigger mass than our sun! The temperature on the surface can be from 20,000 kelvin to 50,000 kelvin. While our own suns average temperature is 6,000 kelvin.

Unfortunately I don't know the second part question
