Planetary System Evolution Using Genetic Algorithms

Abstract:

This project describes the development of genetic algorithms to create planetary system models which closely match real planetary systems nearby to Earth.  A target star's brightness over time is recorded by NASA's satellites, with periodic dips in brightness due to a planet occluding the star. The genetic algorithm creates planetary systems and simulates the brightness of the generated star and calculates the dips in brightness due to its planets, and compares the resulting lightcurve to that of the target star.  A simulated system's lightcurve  closely matching the target star's lightcurve implies that the characteristics of the planets in the simulated system closely match those characteristics of the planets in the target system.
