make_env

This test case checks the creation and stability of a pure iron neutron star envelope.

This test case has 1 part. Click to see a larger version of a plot.

  • Part 1 (inlist_env_header) first creates an initial neutron star envelope through its significant run_star_extras.f90 and saves the result as start.mod. This initial model is then loaded and the evolution begins. The envelope should remain stable - no changes in the thermodynamic or structure profiles - over the 10 million year evolution.
