Radial velocities of red giants in {omega} Cen

We present the results of a survey of radial velocities over a wide region extending from r~=10 out to 80' (~1.5 tidal radii) within the massive star cluster omega Centauri...本研究报道了针对大质量星团半人马座ω星团(omega Centauri)内，从r≈10延展至80角分（约1.5倍潮汐半径(tidal radius)）的宽视场区域开展的径向速度(radial velocity)巡天所得结果。
