Octofitter: Fast, Flexible, and Accurate Orbit Modeling to Detect Exoplanets

AuthorUpdate time

This team has developed a fast and differentiable multimethod orbit-modeling and planet detection code to handle the next-generation of exoplanet detection and characterization.

Package: sefffal/Octofitter.jl

Their techniques include state-of-the-art Bayesian inference techniques to combine direct imaging, radial velocity, and interferometry data of exoplanets close to their host stars. Check out their series of papers below to see it in action on real exoplanetary systems.
