The trigger mechanism of the energy release of solar flares is still unknown. This work provides additional evidence on the involvement of exotic particles like axions and/or other WISPs. The axion scenario suggests a dynamical behaviour behind white-light (WL) solar flares, which results to the measured spectral shape, and, the timing between visible-UV light and soft X-rays. Similarly, axions converted some 1000 km inside the photosphere with a rest mass of ~17 meV fit the...
