脉泽极化与磁场的研究进展

A Review of Maser Polarization and Magnetic Fields

W. H. T. Vlemmings

摘要:

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、行星状星云(PNE)、大质量恒星形成区和超新星遗迹周围的磁场强度强度和形态的深入了解。最近,脉泽观测甚至被用来确定巨脉泽星系中的磁场。本文将介绍近几年来脉泽偏振观测和磁场测量的概况,并讨论磁场测量对几个重要研究领域的影响,如非球面PNE的产生和大质量恒星的形成。

英文摘要:

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.
