Abstract

The magnetic field of the star HD133880 is modeled assuming a magnetic field structure that is described by two theoretical magnetic dipoles. A comparison of this result with what was found previously using a representation of the phase dependence Be(Φ) employing a dipole+quadrupole+octupole expansion for the structure shows that this scheme leads only to a formal description of the phase dependence, while the terms in the expansion lack physical significance.

HD133880 星（硅）的磁场结构

假设恒星 HD133880 的磁场结构是由两个理论磁偶极子描述的，对其磁场进行了建模。将这一结果与之前使用偶极子+四极子+八极子扩展结构来表示相位依赖关系 Be(Φ)的结果进行比较后发现，这种方案只能对相位依赖关系进行形式上的描述，而扩展中的项则缺乏物理意义。

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.
