STAR COLOR GRAPH Temperature ˚C Remember: - Plot the stars. - Shade in the columns as directed starting on the right side and moving left. - Compare to the H-R diagram and label the star groups. Questions: 1. What is the general relationship between temperature and star brightness? (Hint: The hotter the star…) __________________________________________________________________________ __________________________________________________________________________ 2. What relationship do you see between star color and star temperature? (Hint: Cooler stars are…, hotter stars are…) __________________________________________________________________________ __________________________________________________________________________ 3. How does the sun compare to the other stars on the main sequence? (Hint: The sun’s color is …..What part of the main sequence is it in – upper left, lower left, etc.?) __________________________________________________________________________ 4. What star class does our sun belong to (Look at the Spectral Class letters across the top)? __________________________________________________________________________ 5. A star is classified as being in Class B. What is its color? Temperature? __________________________________________________________________________ 6. We know dwarfs are small—smaller than our sun. How can they be so bright? (Look at their temperature and think about their mass as compared to the sun.) __________________________________________________________________________ __________________________________________________________________________
