| Abstract: |
The output of stellar structure and evolution codes has traditionally been in enormous tabular form. We have extensively modified the public-domain Paczynski Code to provide real-time screen-graphical output for use in undergraduate and graduate courses at the college level. Thus anyone studying the structure and evolution of stars can compute such models of varying mass and composition, and see the results (run of composition, energy generation, and gas properties with mass) presented visually as the evolution through core carbon burning proceeds.It is possible to determine the structure of the gray atmosphere of a star assuming the mixing length theory of convection, including the effects of different mixing length. One can watch as the main- sequence homogeneous model converges. A summary program is included which, at the end of an evolution sequence, will show the various model characteristics as a function of time, and also an H- R Diagram for comparison to real stars. We are currently working on a pulsation code which will allow the user to generate and display eigenfunctions for various modes. |
