Abstract We have proposed that solar ultraviolet and corpuscular radiations may excite photoluminescence and cathodoluminescence of the solid cometary substance including mineral halos of comets. Main characteristics of such possible luminescence and physical mechanisms of these phenomena have considered. Results of the tentative identification of previously unknown cometary emissions and data of laboratory research of meteorites are presented. We have shown as well that cometary solid substance may demonstrate red luminescence - similar of red luminescence by the circumstellar dust. Some other aspects of the problem have also been considered.

固体彗星物质的光致发光和阴极发光

摘要 我们提出太阳紫外线和粒子辐射可能会激发固体彗星物质的光致发光和阴极发光，包括彗星的矿物晕。已经考虑了这种可能的发光的主要特征和这些现象的物理机制。介绍了先前未知的彗星排放物的初步鉴定结果和陨石实验室研究数据。我们还表明，彗星固体物质可能会发出红色光——类似于星周尘埃发出的红色光。还考虑了该问题的其他一些方面。
