对附近几个具有可变径向速度的太阳型矮星进行了监测，以找到它们的光谱轨道。 HIP 179、1989、2981、5276、6439、11218、21443、96434 的轨道要素以及 HIP 28678 和 41214 的暂定轨道已确定。我们讨论了每个天体。四个双线双星中的三个是具有几乎相同成分的双胞胎。所有四个周期小于 10 天的轨道都是圆形的，其余轨道都是偏心的。
Several nearby solar-type dwarfs with variable radial velocity were monitored to find their spectroscopic orbits. Orbital elements of HIP 179, 1989, 2981, 5276, 6439, 11218, 21443, 96434 are determined, as well as tentative orbits for HIP 28678 and 41214. We discuss each of those objects. Three of the four double-lined binaries are twins with nearly equal components. All four orbits with periods shorter than 10 days are circular, the remaining orbits are eccentric.
