Item Modeling Keplerian Orbits of Stars, Brown Dwarfs, and Planets(Northern Kentucky University) Herweck, KendraAny companion object (Star, Brown Dwarf, or Planet) that orbits a star follows a Keplerian Orbit. In our project, we used a mock catalog of companions that was designed to mimic the APOGEE surveys. The goal of our project was to compare the effectiveness of Markov-Chain Monte Carlo (MCMC) techniques with more traditional orbital fitting methods for deriving correct companion orbits from radial velocity data. We investigated how well we could recover orbital parameters as a function of parameter space, and in particular, we focused on the trade-offs between computational time and precision.
