Superflares are very strong explosions observed on stars with energies up to ten thousand times that of typical solar 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.The original nine candidates were detected by a variety of methods. No systematic study was possible until the launch of the Kepler space telescope, which monitored a very large number of solar-type stars with very high accuracy for an extended period. This showed that a small proportion of stars had violent outbursts, up to 10,000 times as powerful as the strongest flares known on the Sun. In many cases there were multiple events on the same star. Younger stars were more likely to flare than old ones, but strong events wer

  • Ein Superflare (engl. flare: Flackern, Fackel) ist eine Eruption auf einem sonnenähnlichen Stern, bei der in einer Stunde eine Energie von 1026 bis 1031 Joule freigesetzt wird. Superflares sind damit bis zu eine Million Mal so energiereich wie die größten bisher beobachteten Sonneneruptionen. Auch von normalen Flares, wie sie in UV-Ceti-Sternen, BY-Draconis-Sternen, FK-Comae-Berenices-Sternen, RS-Canum-Venaticorum-Sternen und wechselwirkenden Algolsternen auftreten, unterscheiden sich Superflares nur durch die Menge der freiwerdenden Energie.

  • In astronomia, un super-brillamento è una violenta eruzione di materia che esplode dalla fotosfera di una stella, con un'energia equivalente a un milione di volte o più quella caratteristica dei comuni brillamenti solari. È stato ipotizzato che tali esplosioni siano prodotte dall'interazione del campo magnetico stellare con quello di un pianeta gioviano in orbita stretta.. (it)
  • 超級閃焰'是在像我們太陽的恆星上可以觀察到的非常強烈的爆炸，它所產生的能量是典型太陽閃焰的百萬倍或更高的水準。有人認為這種噴發可能是恆星磁場與一顆行星，推斷類似於木星，的磁場交互作用產生的。 (zh)
  • Les super éruptions stellaires sont de puissantes éruptions stellaires observées sur des étoiles de type solaire. Détectées pour la première fois au début des années 2000, elles possèdent une énergie 100 fois supérieure à celle d'une éruption solaire typique. Toutes les étoiles ayant des éruptions de ce genre montrent des variations de luminosité quasi périodiques interprétées comme étant de très grandes taches stellaires situées à la surface de l'astre et qui se déplacent par la rotation de ce dernier.

  • Supererupções (superflares) são explosões muito fortes observadas em estrelas, com energias de até dez mil vezes as de erupções típicas do Sol. As estrelas nesta classe satisfazem condições que as tornariam análogas ao Sol, e se esperaria que fossem estáveis por escalas muito longas de tempo. As nove candidatas originais foram detectadas por diversos métodos. Nenhum estudo sistemático foi possível até o lançamento do satélite Kepler, que monitorou um número muito grande de estrelas do tipo solar, com precisão muito alta e por um período extenso. Isto mostrou que uma pequena proporção de estrelas tinham violentas erupções, até 10 mil vezes mais potentes que as mais fortes erupções conhecidas do Sol. Em muitos casos, houve eventos múltiplos na mesma estrela. Estrelas mais jovens tinham maior (pt)
  • Супервспышки — это очень сильные взрывы, наблюдаемые на звёздах с энергией, в десять тысяч раз превышающей энергию типичных солнечных вспышек. Звёзды этого класса удовлетворяют условиям, которые предъявляются к солнечным аналогам, и ожидается, что они будут стабильными в течение очень длительного периода времени. Первоначальные девять кандидатов были обнаружены различными методами. Никакие систематические исследования не были возможны до запуска спутника Кеплер, который в течение длительного периода наблюдал за очень большим количеством звёзд солнечного типа с очень высокой точностью. Это исследование показало, что небольшая доля звёзд производила сильные вспышки, в 10 000 раз более мощные, чем самые сильные вспышки, известные на Солнце. Во многих случаях было несколько супервспышек на одн (ru)
