Pryngles is a Python package intended to produce useful visualizations of the geometric configuration of a ringed exoplanet (an exoplanet with a ring or exoring for short) and more importantly to calculate the light curve produced by this kind of planets. The model behind the package has been developed in an effort to predict the signatures that exorings may produce not only in the light curve of transiting exoplanets (a problem that has been extensively studied) but also in the light of stars having non-transiting exoplanets (the bright side of the light curve).

For the science behind the model please refer to the following papers:
