摘要

利用 GAIA DR3 星表中视差误差小于 20% 的天琴座 RR 变星的运动学数据,研究了太阳附近银河晕的旋转情况。我们采用了两种标准来选择日晕恒星:运动学标准和空间标准。在这两种方法中,我们都证实了光环存在着与银河盘旋转方向相反的微弱旋转,运动学标准的速度为\(4.08 \pm 2.19\) km/s,空间标准的速度为\(9.49 \pm 2.59\) km/s。

Rotation of the Milky Way Halo in the Solar Vicinity Based on GAIA DR3 Catalog

The rotation of the Milky Way halo in the solar vicinity is studied using kinematic data of the GAIA DR3 catalog for RR Lyrae variable stars with parallax errors of less than 20%. Two criteria were used for selecting halo stars: kinematic and spatial. In both approaches, we confirm the existence of weak rotation of the halo in the direction opposite to the rotation of the Galactic disk with velocities of \(4.08 \pm 2.19\) km/s for the kinematic criterion and \(9.49 \pm 2.59\) km/s for the spatial criterion.
