米拉是一个磁尘旋转器吗？
Is Mira a magneto-dusty rotator?
摘要：
我们调查的可能性，磁场可能存在于恒星$o-$ Ceti（以下简称为Mira），该领域发挥了作用，在恒星的质量损失。这里提出的模型是一个应用程序的早期衍生的理论，已成功地用于中等和高质量的演化恒星，现在扩展到低质量的一端。模拟表明，它是可能的，以获得一个混合磁流体动力尘埃驱动风的情况下，米拉，其中的作用，磁场在赤道平面的恒星是动态重要的生产恒星风。从模型中获得的风速和温度似乎与其他地方的结果一致。
英文摘要：
We investigate the possibility that a magnetic field may be present in the star $o-$Ceti (hereafter, Mira) and that the field plays a role in the star's mass loss. The model presented here is an application of an earlier derived theory that has been successfully employed for intermediate and high-mass evolved stars, and is now extended to the low-mass end. The modelling shows that it is possible to obtain a hybrid magnetohydrodynamic-dust-driven wind scenario for Mira, in which the role of a magnetic field in the equatorial plane of the star is dynamically important for producing a stellar wind. The wind velocity and the temperatures obtained from the model appear consistent with findings elsewhere.
