Title: Spectroscopy of a New T dwarf Companion to a Nearby Star

Abstract: We are conducting a survey for substellar companions to nearby stars using mid-IR photometry from the WISE satellite. Through this work, we have discovered one of the coolest directly imaged companions. Although our existing spectroscopy from the IRTF has confirmed the cool nature of this companion, the signal-to-noise is too low for the measurement of an accurate spectral type. Therefore, we propose to use GNIRS to obtain a spectrum with sufficient signal-to-noise for this purpose.
