# Graphing the evolution of stars on an HR diagram with timesteps

I have found countless images regarding the evolution of stars, plotted on an HR Diagram, like so (found on Wikipedia):

Although this displays the time in each stage, it does not include any points plotted, relating to a timestep (i.e. 1 billion years), except for the zero age point. Is there anywhere I can find some .csv files that regard stellar evolution?

NB: An example .csv file format would be temperature, radius, mass, luminosity, time.

• Not quite what you want but Star in a Box lets you view the evolution and start and stop it. There is a 'Data Table' link available which will give a CSV files (switch to 'Advanced' for more stages). Otherwise there is the MESA Web front end to the MESA stellar evolution code might produce what you want May 15 at 1:10
