The Solar Photon Random Walk Model simulates the path of photons in radiative transport as they escape from the Sun. Photons do not travel in a straight line, but rather collide with larger particles and get redirected. This simulation models that process using a random walk in polar coordinates. The random walk parameters are adjustable to match different models of the structure of the sun, or the user can input their own values.

The Solar Photon Random Walk Model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_comp_phys_photon_random_walk.jar file will run the program if Java is installed.

This model adds the feature of running numerous photons and compiling average statistics for these photons.
