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.

不同年龄星团中的磁性恒星。2疏散星团IC 4756, \(\boldsymbol{\alpha}\) Per和NGC 7092

本文介绍了对IC 4756、\(\alpha\) Per、NGC 7092三个疏散星团中19颗化学性质特殊恒星的磁场测量结果。利用SAO RAS 6 m BTA望远镜上的主恒星摄谱仪(MSS)获得了80多个圆偏振辐射光谱。研究发现，这些星团的磁场值比年轻猎户座OB1星团的磁场值小三倍以上。显然，在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。
