Nearby, young moving groups (NYMGs) are young, loose, and gravitationally unbound stellar associations within 150 pc from the Sun. Due to their proximities and youths, members of NYMGs are optimal targets for direct exoplanet imaging, in-depth studies of stellar/planetary atmospheres and disks, initial mass function, age calibration of young stars, and history of the vicinity of the Sun. As an important benchmark NYMG, the members of beta-Pictoris moving group (BPMG) have been extensively searched. However, more low-mass members are still expected to be identified. The low-mass members of BPMG are even more interesting because they are expected to have fully convective interiors. Young, fully convective stars are located mostly at large distances from Earth, and BPMG lowest mass members are naturally the best targets to study this important interior transition. We identified low-mass BPMG candidate members from Gaia EDR3 using our own membership calculation scheme, which effectively identifies candidate members using stars' positions and motions in 3-D spaces. Among ~1.5 millions of nearby low-mass stars, we have identified 59 candidate members of BPMG. In this observation, we intend to measure radial velocities of these candidate members to confirm/reject their memberships to BPMG. We request 4.6 hours of spectroscopic observations with Gemini/IGRINS.
