  A previously unremarked star in the constellation Cygnus has,in the past
year,become known as the most mysterious star in our Galaxy.Boyajian's star
exhibits puzzling episodes of sporadic deep dimming discovered in photometry
with the Kepler Mission. Proposed explanations have focused on its obscuration
by colliding exoplanets, exocomets, and even intervention of alien
intelligence. These hypotheses have considered only phenomena external to the
star because the radiative flux missing in the dimmings was believed to exceed
the star's storage capacity.We point out that modeling variations in solar
luminosity indicates that convective stars can store the required fluxes. It
also suggests explanations for a reported time profile asymmetry of the
short,deep dimmings and for a slower,decadal scale dimming reported from
archival and Kepler photometry. Our findings favor a broader range of
explanations of Boyajian's star, that may produce new insights into stellar
magnetoconvection.
