Title: Determining Intrinsic Characteristics of Potential Disk-hosting dM Stars and YSOs from Disk Detective with ARCoIRIS

Abstract: M dwarfs are highly critical targets for discovering and characterizing small exoplanets. However, little is known about how these planetary systems form, and very few bright disk-hosting M dwarfs have been identified. textbf{We propose to use ARCoIRIS observations to determine accurate spectral types, luminosity classes, metallicities, and ages of 16 M stars with significant infrared excesses that have been newly identified as potential nearby ($mathbf{sim 11-170 pc}$) M dwarf disk hosts by the Disk Detective project.} These spectra will yield spectral types and luminosity classes for these targets, and will allow us to determine ages based on their gravity and the presence of Br $gamma$ emission due to disk accretion. These observations will provide useful insight into the occurrence rate of warm disks around these stars, and will be a key component of the first large-scale full- sky survey for M dwarfs with IR excess with WISE.
