Stars

Simulation tools related to stars and stellar evolution include:
  • MESA Binary - iADD's custom binary stellar evolution simulator, built with MESA
    • For background about our tool, please see the background page.
    • For information about how MESA Binary works and each of the controls, please see the information page.
    • MESA Binary also comes with a python package to help users plot data; instructions for installation can be found here.
    • Instructors can find materials on the community Zenodo page or on our For instructors page.

  • stellar - a rapid stellar evolution simulator
    • stellar, one of the original Digital Demo Room simulations, is based on the SSE tool by Jarrod Hurley. It uses models based on precomputed stellar evolution histories to estimate the evolutionary tracks of stars with arbitrarily chosen masses and metallicities. This code is fast but not highly accurate. Because it is fast, it can be used to simulate the evolution of large numbers of stars under different assumptions about the star formation history of a galaxy -- a task known as population synthesis.
