论文摘要
我们使用StreamFinder算法介绍了GAIA数据版本2（DR2）和早期数据版本3（EDR3）目录中检测到的恒星流的地图。我们还报告了使用高分辨率CFHT/Espadons和VLT/UVES光谱仪以及中分辨率NTT/EFOSC2光谱仪获得的亮度DR2流的光谱随访。在DR2（命名为HRID和Gunnthra）中检测到没有明确祖细胞的两个新的恒星流，在EDR3中检测到7个（命名为GAIA-6为GAIA-12）。还确定了几个候选流。该软件还发现与15个球状簇NGC 288，NGC 1261，NGC 1851，NGC 1851，NGC 2298，NGC 2808，NGC 2808，NGC 3201，M 68，M 68，M 68，$ω$ CEN，NGC 5466，NGC 5466，PALOMAR 5，M 5，M 5，M 5，M 5，NGC 6101，M 92，NGC 662，NGC 6.69999. Stellar流将在本系列的后续贡献中使用，以绘制银河加速度字段的属性$ \ sim $ 100 $ 100 pc to $ \ sim $ \ sim $ 100 kpc秤。
We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We also report the spectroscopic follow-up of the brighter DR2 stream members obtained with the high-resolution CFHT/ESPaDOnS and VLT/UVES spectrographs as well as with the medium-resolution NTT/EFOSC2 spectrograph. Two new stellar streams that do not have a clear progenitor are detected in DR2 (named Hrid and Gunnthra), and seven are detected in EDR3 (named Gaia-6 to Gaia-12). Several candidate streams are also identified. The software also finds very long tidal tails associated with the 15 globular clusters NGC 288, NGC 1261, NGC 1851, NGC 2298, NGC 2808, NGC 3201, M 68, $ω$Cen, NGC 5466, Palomar 5, M 5, NGC 6101, M 92, NGC 6397 and NGC 7089. These stellar streams will be used in subsequent contributions in this series to chart the properties of the Galactic acceleration field on $\sim$ 100 pc to $\sim$ 100 kpc scales.
