Superflares are very strong explosions observed on solar-like stars with energy production rates at levels one million times or more than that of typical solar-like flares. The stars in this class satisfy conditions which should make them solar analogues, and would be expected to be stable over very long time scales. It has been suggested〔 〕 that these eruptions may be produced by the interaction of the star's magnetic field with the magnetic field of a putative Jupiter-like planet. ==Superflare stars== A Superflare star is not the same as a Flare star, which usually refers to a very late spectral type red dwarf. The term is restricted to large transient events on stars that satisfy the following conditions: * The star is in spectral class F8 to G8 * It is on or near the main sequence * It is single or part of a very wide binary * It is not a rapid rotator * It is not exceedingly young Essentially such stars may be regarded as solar analogues. , nine superflare stars have been found, some of them similar to the Sun.〔 The energy released during such a flare is 100 times to 10 million times that of the sun's largest coronal mass ejections.〔 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「superflare」の詳細全文を読む スポンサード リンク
