Introducing PHOEBE: An Eclipsing Companion Modeling Software Package

Abstract

One of the primary ways that we can detect stellar companions is by looking for transits. A transit is when the companion passes in front of or behind its host star. In this poster, we will introduce the Python package PHOEBE as well as present the different visualizations of the model that PHOEBE is capable of creating for a given transiting system. Our model can be visualized in four different ways: mesh model, photometric lightcurve, radial velocity curve, and astrometric orbit. We will ultimately use this package to analyze data from the APOGEE and TESS surveys.
