摘要

根据已公布的磁场大小数据，构建了具有各种特殊类型的磁性恒星 HD57682 和 HD81009 的磁场模型，并获得了它们的磁场参数。与其他热天体一样，在HD57682中也观察到磁赤道区域和磁极附近区域的物理条件存在差异，这些差异尚未得到解释。就其特性而言，HD81009 星是 SrCrEu 型磁性恒星的典型代表，但它是双星。

Magnetic Field Structures of Chemically Peculiar Stars. I. HD57682, HD81009

Based on published data on the magnitudes of the magnetic field, models of the magnetic field of magnetic stars of various types of peculiarity HD57682 and HD81009 are constructed and the parameters of their magnetic fields are obtained. In HD57682, like other hot objects, differences are observed in the physical conditions in the region of the magnetic equators and in the regions near the magnetic poles, which have not yet been interpreted. In terms of its properties, the star HD81009 is a typical representative of magnetic stars of the SrCrEu-type, except for is binary character.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
