Five solar Mass Star 0.25 0.5 0.75 1.0 Star’s Lifetime ________________ Notes: Using the information above, work with your group to construct a comprehensive graph showing changes over time in the star’s central density, temperature, pressure, surface temperature, luminosity, etc. Use a key, the notes section above or other means to clarify what the graph means for a reader.Prepare the graph to turn in as a group. Individual Conclusion – post in submission box on Blackboard: A. Compare a one solar mass star to the 5 solar mass star, looking at what is different and what is the same.
