通过偏振观测，脉泽是对各种不同天体中磁场的独特探测，不同的脉泽种类追踪不同的物理条件。近年来，脉泽偏振观测提供了对演化恒星、行星星云(PNE)、大质量恒星形成区域和超新星遗迹周围的磁场强度和形态的洞察。最近，脉泽观测甚至被用来确定巨型激光星系中的磁场。本文将对近几年来的脉泽偏振观测和磁场测量进行综述，并讨论磁场测量对几个重要研究领域的意义，如非球面PNE的产生和大质量恒星的形成。
Abstract Through polarization observations masers are unique probes of the magnetic field in a variety of different astronomical objects, with the different maser species tracing different physical conditions. In recent years maser polarization observations have provided insights in the magnetic field strength and morphology in, among others, the envelopes around evolved stars, Planetary Nebulae (PNe), massive star forming regions and supernova remnants. More recently, maser observations have even been used to determine the magnetic field in megamaser galaxies. This review will present an overview of maser polarization observations and magnetic field determinations of the last several years and discuss the implications of the magnetic field measurements for several important fields of study, such as aspherical PNe creation and massive star formation.
