STELLAR

(From "Astrophysics Simulations", by Danby, J.M.A., Kouzes, R., & Whitney, C., Wiley, 1995.)


The program STELLAR is used to calculate the interior model of a star. It integrates the four differential equations (for Temperature, Density, Radius, and Luminosity), with a simple equation of state, approximate opacity treatment, and physics appropriate for most ZAMS stars. Thus it is a good illustration to the basic concepts of stellar structure; we leave the details for later in the course.
You can run STELLAR on the 486 PC in the computer room (A 111). Switch on the computer (on your left side) and the monitor. Wait for it to reboot; it will be in C: drive when done. If already on, go to C: drive. Go to subdirectory CUPS/CUPSAS (use chdir). Here all computer codes reside. Go to subdirectory STELLAR and type STELLAR. Under menu item [File] you can read about the code and how to use it.

Walk-Through STELLAR Program

The program initially comes up with the help screen. A mouse click or keyboard sroke will bring up the menu bar. Here are some hints on running STELLAR.
