The four directly imaged planets orbiting the star HR 8799 are an ideal laboratory to probe atmospheric physics and formation models. We present more than a decade's worth of Keck/OSIRIS moderate spectral resolution (R=4,000) of HR 8799 b, c, and d. This includes: detection of molecules, planetary radial velocity, and ...
