相对于惯性坐标系的剩余HCRF旋转
Residual HCRF Rotation relative to the Inertial Coordinate System
摘要：
利用VLBI测量了23颗射电星的绝对自行。这些是有脉泽辐射的恒星，或者是非常年轻的恒星，或者是渐近巨星分支恒星。通过与依巴谷天体参考系（HCRF）光学星表的恒星自行比较，我们得到了该参考架相对于惯性坐标系的剩余旋转矢量分量：（ω_x，ω_y，ω_z）=（-0.39，-0.51，-1.25）+/-（0.58，0.57，0.56）mas/yr。根据现有资料，我们确定了光学实现HCRF相对于惯性坐标系的剩余转动矢量分量的新值：（ω_x，ω_y，ω_z）=（-0.15，+0.24，-0.53）+/-（0.11，0.10，0.13）mas/yr。
英文摘要：
VLBI measurements of the absolute proper motions of 23 radio stars have been collected from published data. These are stars with maser emission, or very young stars, or asymptotic-giant-branch stars. By comparing these measurements with the stellar proper motions from the optical catalogs of the Hipparcos Celestial Reference Frame (HCRF), we have found the components of the residual rotation vector of this frame relative to the inertial coordinate system: (ω_x,ω_y,ω_z) = (-0.39,-0.51,-1.25)+/-(0.58,0.57,0.56) mas/yr. Based on all the available data, we have determined new values of the components of the residual rotation vector for the optical realization of the HCRF relative to the inertial coordinate system: (ω_x,ω_y,ω_z) = (-0.15,+0.24,-0.53)+/-(0.11,0.10,0.13) mas/yr.
