摘要

我们继续每年发表化学上特殊的恒星的磁场测量结果。2016年，SAO RAS 6米望远镜的主恒星摄谱仪进行了观测。我们得到了64颗恒星的108对圆偏振光谱。在5个天体（HD 9050、HD 31592、HD 82093、HD 142502和HD 190068）中，首次发现了磁场。我们估计了所有物体的物理参数（有效温度\(T_{\textrm{eff}}\)，表面重力\(\log g\)，预计旋转速度\(v_{e}\sin i\)）和径向速度\(V_{r}\)。

Results of Magnetic Field Measurements with the 6-m BTA Telescope X. Observations in 2016

We continue the annual publications of the magnetic field measurements of chemically peculiar stars. Observations were carried out with the Main Stellar Spectrograph of the 6-m telescope at SAO RAS in 2016. We obtained 108 pairs of circularly polarized spectra for 64 stars. For five objects (HD 9050, HD 31592, HD 82093, HD 142502, and HD 190068), a magnetic field was discovered for the first time. We estimated the physical parameters (effective temperature \(T_{\textrm{eff}}\), surface gravity \(\log g\), projected rotation velocity \(v_{e}\sin i\)) and the radial velocity \(V_{r}\) for all the objects.
