[PEM12-25] Comparison of Solar and Stellar White-light Flares
Keywords:solar flares, superflares, magnetic reconnection
We present here a comparison of solar and stellar “white-light” flares on the relation between the flare energies and durations. The comparison of the same wavelength emission (visible continuum) can directly approach that of the energy release mechanism of solar and stellar flares.
The result shows that the durations of solar white-light flares are one order of magnitude longer than that expected by the t-E relation of stellar superflares. The discrepancy may imply the different physical properties of solar and stellar flares such as (1) flare emission / cooling mechanism or (2) magnetic field strength.
We consider that this difference between solar and stellar flare can become a clue not only to the environment of stellar superflares but also to the possibility of superflares on our Sun.
