磁场与天体物理脉泽辐射的极化

Magnetic Fields and the Polarization of Astrophysical Maser Radiation: A Review

William D. Watson

摘要:

描述了磁场和偏振脉泽辐射之间关系的基本方面,重点解释了观测到的光谱。特别注意了三个问题--Goldreich,Keeley & Kwan(1973)经典解的适用性的局限性,即当塞曼分裂远小于谱线宽度时,由圆极化推断磁场的强度(特别是对于SiO脉泽),和塞曼三重态的组件的情况下,在OH脉泽的恒星形成区域的光谱的意义。

英文摘要:

Basic aspects of the relationship between the magnetic field and polarized maser radiation are described with the emphasis on interpreting the observed spectra. Special attention is given to three issues--the limitations on the applicability of the classic solutions of Goldreich, Keeley & Kwan (1973), inferring the strength of the magnetic field from the circular polarization when the Zeeman splitting is much less than the spectral linebreadth (especially for SiO masers), and the significance of the absence of components of the Zeeman triplet in the spectra of OH masers in regions of star formation.
