The table below contains 5 objects, some of which are main sequence stars and some of which are protostars. Please plot the objects on the provided Hertzsprung-Russell Diagram above and attached as a JPEG file. Use the H-R Diagram to answer the following questions and Content Slides to help with this. Put each of your answers on its own line. You do not need to turn in your H-R D; it is just to help you find the answers. Stars and Protostars Object Spectral Class Absolute Magnitude V K6 +6 W A4 -4 X G7 +2 Y M1 +3 Z 09 -6 1. Which objects (V, W, X, Y, Z) are protostars? 2. Which protostar(s) will form a high mass star? That means which one or more will become O, B, or A main sequence stars. 3. Which protostar will take the longest time to become a star? 4. The Luminosity of both a star and a protostar in the H-R D depends on their Surface Temperature and Radius. If you like equations, it looks like this: L = 4πR² σT4 That mean radius R² x T4 In this question, you will decide how luminosity and temperature affect the size. The two sentences from the Week 3 Math Shortcut will help with this. In the H-R Diagram, compare object V and object Y. a. Which object has the bigger temperature, V or Y? b. Which object has the bigger luminosity, V or Y? c. Based on your answers to a and b, which object has the bigger radius? d. Is your answer what you expected based on what you learned about how stars formed in the Content Slides? Why or why not? Which Content Slide tells you this? 5. Which image in the Content Slides this week was your favorite? Let me know which slide number your choice is so I can find it easily. Tell us why you liked it in at least two full sentences. Based on your answers to a and b, which object has the bigger radius? Is your answer what you expected based on what you learned about how stars formed in the Content Slides? Why or why not? Which Content Slide tells you this?
