A New Moving Group in the Local Arm
Abstract
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.
