It is situated in the southern equatorial constellation of Hydra. Visually Tol 1247 appears to be an irregular or possibly a barred spiral galaxy. Tol 1247 is named after the surveys that were carried at the Cerro Tololo Inter-American Observatory (CTIO), the first of which was in 1976. It is one of only two galaxies in the local universe known to emit Lyman Continuum photons (LyC).〔 ==Background== Tol 1247-232 first appeared in the literature in 1985. These observations were carried out using the IR photometer at the CTIO 4m telescope (renamed the Victor Blanco telescope). The aim of the study was to take Near Infrared broad band photometry of Violent Star Formation Regions.〔 The NASA/IPAC Extragalactic Database (NED) gives 28 citations for the original Melnick et al. 1985 paper.〔(【引用サイトリンク】 url=http://ned.ipac.caltech.edu/cgi-bin/datasearch?search_type=Ref_id&objid=109944&objname=TOLOLO%201247-232&img_stamp=YES&hconst=73.0&omegam=0.27&omegav=0.73&corr_z=1&of=table )〕 Six years later it was identified as an HII galaxy in the paper 'A spectrophotometric catalogue of HII galaxies', a study of 425 emission-line galaxies. Tol 1247 has also been classified as a Starburst galaxy, a Blue Compact Dwarf and a Wolf-Rayet galaxy.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tololo-1247-232」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
