ReflectX

ReflectX is a suite of planet reflected light spectra generated from PICASO and VIRGA for detecting and characterizing directly imaged exoplanets in reflected light using MagAO-X, ELTs (ELT-PCS, ELT-ANDES and GMagAO-X), and HWO.

Currently ReflectX version 1 offers a grid of equilibrium gas giant models spanning star and planet parameters, see the Gas Giant Grid page for more. If you want a bespoke model of a specific planet, please email Logan Pearce lapearce@umich.edu and we’re happy to collaborate!
