Title: Reconnaissance of Young M Dwarfs: Confirming 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 are carrying out a search for new young moving group members from a sample of ~2000 X-ray and UV-selected active M dwarfs. Using an efficient method to identify moving group members, we have uncovered 297 new candidates of seven young associations spanning the entire sky. Here we propose radial velocity observations of 141 stars visible in 2014B to confirm group membership, a critical step prior to deep adaptive optics imaging to search for giant planets. 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.
