论文摘要
我们提出了一个新的移动组，该小组聚集在运动学，空间位置和元素丰度中。它的空间位置位于银河系当地臂的中心。采用收敛点方法来选择候选成员星。\ textbf {在206个候选成员星中，有74个是前序列恒星，其中一些是具有出色的磁盘。}我们假设那些序列序列星属于猎户座星云。我们建议该移动组是由经过的局部臂的密度波引起的。
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.\textbf{ 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 Orion nebula. We suggest this moving group is caused by density wave of the Local Arm passing by.
