Abstract—We present the results of observations of radial velocity variability in stars with exoplanets. Observations of a number of stars with characteristic stellar magnitudes from 8.54^m to 10.5^m were carried out using a new high-resolution (R = 35 000–120 000) fiber-fed spectrograph mounted at the foundation of the 6-m BTA telescope, in the mode of resolutions from R = 45 000 to R = 65 000 with a simultaneous registration of the calibration spectrum of a thorium–argon hollow cathode lamp. The achieved characteristic measurement accuracies ranged from a few to several tens of m s⁻¹. In the future, the thorium-argon lamp will be supplemented with a Fabri–Perot etalon to reach the radial velocity measurement accuracy in stars up to 1 m s⁻¹.

摘要—我们介绍了系外行星恒星径向速度变化的观测结果。从8开始观测到许多具有特征恒星的恒星。54^米至10 。5^米进行了使用新的高清晰度（[R = 35 000-120 000）的光纤馈送摄谱仪安装在6米BTA望远镜的基础上，在分辨率从所述模式- [R = 45 000〜- [R = 65 000同时注册registration-氩空心阴极灯的校准光谱。达到的特性测量精度范围从几毫秒到几十毫秒^-1。将来，the氩灯将补充有Fabri-Perot标准具，以达到高达1 ms ^-1的恒星径向速度测量精度。
