Abstract

We present a possible NASA key project using the iSHELL near-infrared high-resolution echelle spectrograph on the NASA Infrared Telescope Facility for precise radial velocity follow-up of candidate transiting exoplanets identified by the NASA TESS mission. We briefly review key motivations and challenges with near-infrared radial velocities. We present the current status of our preliminary radial velocity analysis from the first year on sky with iSHELL.
