Abstract

This paper presents the results of magnetic field measurements for 19 chemically peculiar stars in three open star clusters IC 4756, \(\alpha\) Per, NGC 7092. More than 80 spectra of circularly polarized radiation were obtained with the Main Stellar Spectrograph (MSS) at the 6-m BTA telescope of SAO RAS. It was found that the magnetic field value in these clusters is more than three times less than in the young Orion OB1 association. Apparently, unique conditions developed in this association allowed the generation of super-strong magnetic field during the formation of stars.

摘要

本文介绍了三个疏散星团 IC 4756、\(\alpha\) Per、NGC 7092 中 19 颗化学奇特恒星的磁场测量结果。使用主恒星摄谱仪 (MSS) 获得了 80 多个圆偏振辐射光谱）在 SAO RAS 的 6 米 BTA 望远镜上。研究发现，这些星团中的磁场值比年轻的猎户座 OB1 星团中的磁场值低三倍多。显然，这种关联中形成的独特条件允许在恒星形成过程中产生超强磁场。
