Outline of Final Research Achievements

Objective physical information on astronomical objects is generally obtained from the analysis of spectra through spectroscopic observations. Comprehending the spectra of astronomical objects is intricate, but their colors are visually impressive. Therefore, direct observation of these spectra would provide an intuitive understanding of their essential characteristics. With this perspective, we have developed Spectroscopic Eyepiece System 2(SPEYE2), which enables simultaneous visual observation of both the color and spectrum of astronomical objects. This system has been integrated into a telescope suitable for visual observation. Moreover, we have developed spectroscopic images and supplementary materials to enhance comprehension of spectroscopic data.

Academic Significance and Societal Importance of the Research Achievements

人間の眼は暗い対象に対して色を検知する能力が低下することから天体スペクトルの観察には大口径の望遠鏡での設置が優位となる。ぐんま天文台１５０ｃｍ望遠鏡の集光力を生かすことで、天体の色のみならず、天体の分光スペクトルの詳細な特性を視覚的に検知することが可能となった。公共天文台であるぐんま天文台では夜間の観望会に多くの来館者がある。そこで、天体のスペクトルを観察することで天体の分光観測にもとづく天体物理学の基礎を、視覚を通じて直観的に学べる教育機会を提供することが可能となった。
