- H-R Diagram
This simulation shows the difference in the evolution stages and evolution times of an intermediate mass star of 3 solar masses versus a high mass star of 15 solar masses. Note that the evolution tracks are on in this simulation.
Our simulation begins with stars plotted on the main sequence. On the HR diagram, the main sequence is an almost straight line from the upper left to the lower right region of the diagram. We do not concern ourselves with showing any of the very short-lived proto-stellar evolution; stars begin on the main sequence where they spend most of their ...
This page gives an intermediate level interface to the simulations, and is primarily for undergraduates who have some knowledge of stars and stellar evolution. The user will be able to create simulations based on the mass and metallicity parameters of the stars.
Exercise six focuses on stellar properties and evolution for individual stars and for stel-lar clusters. It begins with observables such as stellar brightness and color, and uses the Hertzsprung-Russell (H-R) Diagram as a vehicle to track how stellar properties change with age.
The most detailed stellar evolution codes solve the underlying (1D) differential equations for stellar structure and evolution (for details, see Eggleton 2006). They advance the nuclear burning and stellar structure equations at every time step, and by taking energy transport and nuclear energy generation into account, they converge to a time ...
The Stellar Structure and Evolution Simulator section of the Digital Demo Room gives you background information on stellar evolution, movies of stars moving through the HR diagram, and even lets you create your own movies.
