摘要

第二部分综述了Mira变星在光学和近红外波段的光谱观测。估计了各种结构(大气、包层)在光谱形成中的作用。根据两种模型近似估计了产生观测到的发射光谱畸变效应的分子层厚度。假设相当一部分光谱是在星周包层中形成的，讨论了已知的光度和光谱效应。

Mira Variables. Molecular Spectra

We present the second part of the review of spectroscopic observations of Mira variables in the optical and near infrared. The role of various structures (atmosphere, envelopes) in the formation of the optical spectrum is estimated. The thickness of the molecular layer that creates the observed effects of distortion of the emission spectra is estimated based on two model approximations. Assuming that a significant part of the optical spectrum is formed in the circumstellar envelopes, the known photometric and spectroscopic effects are discussed.
