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 σT¼ That mean radius R² ∞ — In this question, you will decide how luminosity and temperature affect the size. The two sentences α 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?
