| 英文摘要 | Using Large Sky Area Multi-object Fibre Spectroscopic Telescope spectroscopic data, we find a strong signal of a comoving group of stars in the constellation of Draco. The group, observed near the apocenter of its orbit, is 2.6 kpc from the Sun with a metallicity of -0.64 dex. The system is observed as a streaming population of unknown provenance with mass of about 2.1 +/- 0.4 . 10(4) M-circle dot and brightness of about M-V similar to -3.6. Its high metallicity, diffuse physical structure, and eccentric orbit may indicate that the progenitor satellite was a globular cluster rather than a dwarf galaxy or an open cluster. |
