Abstract: 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 unexpected soft X-ray emission from the quietest Sun in 2009, i.e., the manifestation of the solar corona problem. Chameleons behave similarly, but they couple to photons enhanced in vacuum, i.e., in the magnetized empty outer space, since their coherent conversion length stretches with better vacuum.
