Extra-solar Planets via Bayesian Fusion MCMC

Chapter
Part of the Springer Series in Astrostatistics book series (SSIA, volume 1)

Abstract

A Bayesian multi-planet Kepler periodogram has been developed based on a fusion Markov chain Monte Carlo algorithm (FMCMC). FMCMC is a new general purpose tool for nonlinear model fitting. It incorporates parallel tempering, simulated annealing and genetic crossover operations. Each of these features facilitate the detection of a global minimum in chi-squared in a highly multi-modal environment. By combining all three, the algorithm greatly increases the probability of realizing this goal.
