Laughlin, may appear in the future of the Universe when the metallicity of the interstellar medium is several times the solar value. == Characteristics == Due to opacity effects, as metallicity of the interstellar gas increases both the maximum and minimum masses a star can have will decrease. For the latter case, it's expected that an object with a mass of 0.04 solar masses (40 times the mass of Jupiter), that currently would become a brown dwarf unable to fuse hydrogen, could do so ending in the main sequence with a surface temperature of 0 °C (273 K, thus ''frozen''), much cooler than the dimmest red dwarfs of today, and water ice clouds forming in its atmosphere. The luminosity of these objects would be more than a thousand times smaller than the faintest stars currently existing and their lifetimes would be also sensibly longer. 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「Frozen star (hypothetical star)」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.
