摘要：We present a new moving group clustered in kinematics, spatial position, and elemental abundances.Its spatial position is around the center of the Local Arm of the Milky Way.A convergent point method was taken to select candidate member stars.Among 206 candidate member stars, 74 are pre-main-sequence stars and some of them have stellar disks.We presume those pre-main-sequence stars belong to the Orion nebula.We suggest that this moving group is caused by the density wave of the Local Arm passing by.
