Assignment

Part 1

The young white dwarfs in the globular cluster 47 Tuc have a mass of 0.53 solar masses. The turn-off stars (those leaving the main sequence now) have a mass of 0.9 solar mass. The metallicity of 47 Tuc is 0.0033. Use 1MS_prems_towd Can you find values of the wind parameters

  Reimers_wind_eta
  Blocker_wind_eta 

that yield the initial-final mass relation for 47 Tuc? Are these values unique? What is different about choosing different values, if there is a difference? How could you tell what the stars are actually doing?

Part 2

Write your own run_star_extras.f so that you can vary the neutrino production rates by a constant factor that you can give in your inlist file.
