PART 3

- Follow the evolution for five stars with different masses. Complete the table below filing in a row for each mass.

PART 4

Compare the data table for a range of stars.

1. Are more massive stars the brightest and hottest types of srar for their whole lives?

2. Which mass star gets the hottest?

3. Which mass star gets the coolest?

4. Which mass star becomes the most luminous?

 

PART 5:

Deneb and Betelgeuse are both 20x the maws of the Sun, but look very different. Deneb has 100 times the radius of the Sun and its temperature is about 8000K. Betelgeuse has 1000 times the radius of the Sun and its temperature is about 3500K,

 

   1. What stages of their lives are the two stars in?

   2. How long does each star have to live?
