10. What type of star has a high temperature and a high luminosity?
11. What type of star has a low temperature but a high luminosity?
12. What type of star has a low temperature and a low luminosity?
13. Plot the stars A – E on the HR Diagram shown on the first page. Use the drawing tools in this Word doc to draw the letter of each star in roughly the position it will fall on the HR Diagram. Once plotted determine the color of each star.
# HR Diagram Worksheet
## Introduction
The Hertzprung-Russell diagram is a graph relating stars' temperature to their brightness (luminosity). The graph has 5 main regions, each for a different group of stars:

Step 1I'm here to help! However, I noticed that questions 10 to 12 are conceptual and do not require mathematical calculations or LaTeX notation.
I'll answer those three questions first, and then we can move on to question 13, which requires plotting stars on an HR diagram.
Step 2
A star with a high temperature and high luminosity is most likely a main sequence star, specifically, an O or B type star. These stars are massive and burn through their nuclear fuel quickly, making them both hot and bright.
Final Answer
Once the stars are plotted, you can determine their colors based on their positions on the HR diagram. Generally, hotter stars are bluer, and cooler stars are redder. You can use the provided HR diagram as a reference to estimate the colors. When you provide the temperature and luminosity values for stars A – E, I will help you plot them on the HR diagram and determine their colors.
