发现Ap Si星HD 133880具有非常非正弦的磁场曲线。有人认为，这颗恒星是极少数具有主要非偶极场几何形状的Ap恒星之一。使用共线偶极子和四极子可以找到一种可能再现观测到的磁曲线的模型族；这些模型表明，四极磁场分量至少是偶极磁场分量的1.3倍。14参。
The Ap Si star HD 133880 is found to have a very nonsinusoidal magnetic field curve. It is argued that this star is one of a very small number of Ap stars that have predominantly nondipolar field geometries. One possible family of models that reproduces the observed magnetic curve may be found using a collinear dipole and quadrupole; these models suggest that the quadrupolar field component is at least 1.3 times larger than the dipolar component. 14 refs.
