标题： The vertex coordinates of the Galaxy's stellar systems according to the Gaia DR3 catalogue

摘要： 我们给出了确定各种恒星系统顶点坐标的结果，这些系统的质心位于银河盘面上。 为此，我们使用了$Gaia$DR3目录中包含的红巨星和亚巨星的位置、视差、自行和径向速度。 在确定局部坐标系中变形速度张量分量时，我们找到了所研究恒星系统的顶点坐标。 结果表明，顶点偏差$l_{xy}$在银河圆柱坐标（$R, \theta$）和银河直角坐标（$X,Y$）中有复杂的依赖关系。 根据本文提出的方法，首次确定了顶点的日心距离。 获得的结果表明，除了银心和恒星系统顶点的角度坐标不一致外，它们的日心距离也不一致。 这可能表明银河系中存在显著影响其轴对称性的结构。 显示英文摘要

摘要： We present the results of determining the coordinates of the vertices of various stellar systems, the centroids of which are located in the Galactic plane. To do this, the positions, parallaxes, proper motions, and radial velocities of red giants and subgiants contained in the $Gaia$~DR3 catalogue have been used. When determining the components of the deformation velocity tensors in local coordinate systems, we found the coordinates of the vertices of the stellar systems under study. It turned out that there is a complex dependence of vertex deviations $l_{xy}$ in Galactocentric cylindrical ($R, \theta$) and Galactic rectangular ($X,Y$) coordinates. Based on the approach proposed in this paper, heliocentric distances to vertices have been determined for the first time. The results obtained show that in addition to the fact that the angular coordinates of the Galactic center and the vertices of stellar systems do not coincide, their heliocentric distances do not coincide as well. This presumably indicates that there are structures in the Galaxy that noticeably affect its axisymmetry.
