You will create a 7 solar-mass star from the 7M_prems_to_AGB test suite

First, recall the various regions on the H-R diagram that you identified in the assignment for the solar mass star. Plot the solar mass star and the 7 solar mass star on the same H-R diagram. How does the behaviour of the two models differ?

Plot the profiles of density, temperature, energy generation (dividing into the various reactions using the burn columns of the profile files) as a function of enclosed mass for the main sequence of the 7 solar-mass star and pick two later stages that you find interesting. Make a plot showing the composition of the different regions with the enclosed mass as the x-coordinate.

Plot temperature against density on a log-log plot to identify the convective and radiative regions. Plot neutrino luminosity as a function of time and compare with the one-solar-mass model (from the history file).
