juliet

../juliet.png

juliet is a versatile modelling tool for transiting and non-transiting exoplanetary systems that allows to perform quick-and-easy fits to data coming from transit photometry, radial velocity or both using bayesian inference and, in particular, using Nested Sampling in order to allow both efficient fitting and proper model comparison.

In this documentation you'll be able to check out the features juliet can offer for your research, which range from fitting different datasets simultaneously for both transits and radial-velocities to accounting for systematic trends both using linear models or Gaussian Processes (GP), to even extract information from photometry alone (e.g., stellar rotation periods) with just a few lines of code.

juliet builds on the work of "giants" that have made publicly available tools for transit (batman, starry), radial-velocity (radvel), GP modelling (george, celerite) and Nested Samplers (MultiNest via pymultinest, dynesty) and thus can be seen as a wrapper of all of those in one. Somewhat like an Infinity Gauntlet for exoplanets.

juliet is in active development in its public repository on GitHub. If you discover any bugs or have requests for us, please consider sending us an email or opening an issue.
