This gas is believed to be generated in collisions among KBO-like parent bodies; however, some systems have gas properties more similar to protoplanetary disks. JWST Cycle 1 NIRSpec observations have recently discovered hot, florescent CO in two of the ALMA CO debris disks. For HD 131488, the detection of florescent CO in the fundamental band suggests the presence of a newly discovered, additional, massive CO component closer to the star. We propose to search for hot, florescent CO in three nearby debris disks, HD 21997, HD 32297, and HD 146897, to better understand the conditions under which florescent CO emission is present and perform a detailed characterization of any detected gas.
