The perturbed photometric-magnetic dynamical model for the sunspot evolution

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We present the perturbed version of the Photometric-Magnetic Dynamical (PhMD) model for describing the sunspot evolution. This involves fluctuating the magnetic flux inflow into the sunspot, by a harmonic perturbation with frequency equal to that of the solar rotation. The nonlinear dynamical system is studied either for the conservative or for the dissipative case.
