Title: Reconnaissance of Young M Dwarfs: Locating the Elusive Majority of Nearby Moving Groups

Abstract: With ages between ~8-120 Myr and distances \lesssim80 pc, young moving group members make excellent targets for detailed studies of pre-main sequence evolution and exoplanet imaging surveys. We propose to finish a low-resolution spectroscopic program started in 2013B to confirm our sample of ~1300 X-ray-selected active M dwarfs, about one-third of which are expected to be members of young moving groups. Our larger program consists of three parts: an initial reconnaissance phase of low-resolution spectroscopy to vet unlikely association members, radial velocity observations to confirm group membership, and deep adaptive optics imaging to study the architecture and demographics of giant planets around low-mass stars. Our observations in 2014A will finish the phase of low-resolution spectroscopy covering the second half of the sky. We will also exploit our rich sample to study the evolution of chromospheric and coronal activity in low-mass stars with unprecedented precision. Altogether, this program will roughly double the population of M dwarfs in young moving groups, providing new targets for a broad range of star and planet formation studies in the near-future.
