In this work, we present a systematic search for stellar groups in the Taurus field by applying the DBSCAN algorithm to the data from Gaia DR2. We find 22 groups, consisting of 8 young groups (Groups 1–8) at ages of 2–4 Myr and distances of ∼130–170 pc, and 14 old groups (Groups 9–22) at ages of 8–49 Myr and distances of ∼110–210 pc. We characterize the disk properties of group members and find 19 new disk-bearing stars, 8 of which are in the young groups with 11 others belonging to the comparatively old groups at the ages of 8–11 Myr. We characterize the accretion properties of the group members with Hα emission lines in their Large Sky Area Multi-Object Fibre Spectroscopic Telescope spectra, and discover one source in Group 10 at an age of 10 Myr which still shows accretion activity. We investigate the kinematic relations among the old groups, find that Group 9 is kinematically related to the known Taurus members, and exclude any kinematic relations between Groups 10–22 and the known Taurus members.

在这项工作中，我们通过将 DBSCAN 算法应用于 Gaia DR2 的数据，对金牛座领域的恒星群进行了系统的搜索。我们发现了 22 个组，包括 8 个年龄为 2-4 Myr 且距离约为 130-170 pc 的年轻组（组 1-8）和 14 个年龄为 8-49 Myr 的老组（组 9-22）和〜110-210 pc的距离。我们描述了群成员的盘特性，发现了 19 颗新的带盘星，其中 8 颗在年轻的群中，另外 11 颗属于年龄在 8-11 Myr 的相对较老的群。我们用 H α 来表征群成员的吸积特性在他们的大天空区域多目标光纤光谱望远镜光谱中发现了发射线，并在 10 Myr 的年龄发现了第 10 组中的一个源，该源仍然显示吸积活动。我们调查了旧组之间的运动学关系，发现第 9 组与已知的金牛座成员在运动学上相关，并排除了第 10-22 组与已知的金牛座成员之间的任何运动学关系。
