Suppose that star formation stopped in the universe today. The aim of this
question is to determine when the last stars will be visible. (a) We can determine that the Main Sequence lifetime of a star of mass M is given by TX M-2.92, M > 0.7MⒸ M<0.7Mo TX M-1.62 When will the last stars die out? (b) What will the scale factor of the universe be at that time? [You may assume that the Sun will have a Main Sequence lifetime of 10¹0 years.]
