Cycle 23 Variation in Solar Flare Productivity

, 2013
The NOAA listings of solar flares in cycles 21-24, including the GOES soft X-ray magnitudes, enable a simple determination of the number of flares each flaring active region produces over its lifetime.

Scaling laws of solar and stellar flares

, 2007
In this study we compile for the first time comprehensive data sets of solar and stellar flare parameters, including flare peak temperatures T_p, flare peak volume emission measures EM_p, and flare durations t_f from both solar and stellar data, as well ...

A New Model of Solar Flares

The Astrophysical Journal, 1964
Abstract : A model is proposed for solar flares, involving a slow build-up of the pre-flare configuration in which gases circulate in the chromosphere and corona. At some stage this configuration becomes unstable and the flash phase of the flare occurs.

Interplanetary shock waves associated with solar flares [PDF]

The interaction of the earth's magnetic field with the solar wind is discussed with emphasis on the influence of solar flares. The geomagnetic storms are considerered to be the result of the arrival of shock wave generated by solar flares in ...

The correlation between soft and hard X-rays component in flares: from the Sun to the stars

, 2007
In this work we study the correlation between the soft (1.6--12.4 keV, mostly thermal) and the hard (20--40 and 60--80 keV, mostly non-thermal) X-ray emission in solar flares up to the most energetic events, spanning about 4 orders of magnitude in peak ...
