Emergence of magnetic flux on the Sun as the cause of a 158-day periodicity in sunspot areas
Article Abstract:
There is a periodic variation in the emergence of magnetic flux on the Sun. This variation is in temporal coincidence with the periodicity seen in high-energy solar flares, thus indicating a close connection between them. Wavelet analysis of sunspot areas indicates that the periodicity found in high-energy solar flares is caused by a periodic emergence of magnetic flux which is coincident both in frequency and time. These findings support the hypothesis that the emergence of new magnetic flux triggers the destabilization of active regions and prompts the occurrence of energetic solar flares.

Characterization of extrasolar terrestrial planets from diurnal photometric variability
Article Abstract:
Research is presented concerning the development of a model which can be used for the the prediction of the features discernible in low-precision photometry. The daily flux variations of plants of similar size to the Earth are discussed.
