EXOFASTv2: A public, generalized, publication-quality exoplanet modeling code

Understand

We present the next generation public exoplanet fitting software, EXOFASTv2.

• It is capable of fitting an arbitrary number of planets, radial velocity data sets, astrometric data sets, and/or transits observed with any combination of wavelengths.
• We model the star simultaneously in the fit and provide several state-of-the-art ways to constrain its properties, including taking advantage of the now-ubiquitous all-sky catalog photometry and Gaia parallaxes.
• EXOFASTv2 can model the star by itself, too.
