With a very faint visual magnitude of 21.05 and a low effective temperature of 2074K it is visible primarily in large telescopes sensitive to infrared light. 2MASS J0523-1403 was first observed as part of the Two Micron All-Sky Survey (2MASS). ==Characteristics== 2MASS J0523-1403 has a luminosity of , a mass of <0.08, a radius of and an effective temperature of 2074K. These values are currently the lowest known for a main sequence star.〔 It has a stellar classification of L2.5 and a V-K color index of 9.42.〔 Observation with the Hubble Space Telescope has detected no companion beyond 0.15 arcsecond. Sporadic radio emissions were detected by the VLA in 2004. H-alpha (Hα) emissions have also been detected, a sign of chromospheric activity.〔 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「2MASS J0523-1403」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.
