The ring current dynamics, characterized by the Dst index, has been studied for thirty years using the Burton et al (1975) equation. The original formula is based on the restriction of the DPS (Dessler, Parker, and Schoppke) theorem and assuming a constant decay time of particles. The decay time parameter is crucial determining the ring current energization, because the energy injection rate is highly sensitive to this parameter. In a previous work, instead of using a constant value, we introduced the decay time of particles in the energy rate balance equation as a continuous function of the absolute value of the pressure corrected Dst index to avoid the reported discontinuities determining it. Here, we extend our previous work to theoretically justify the proposed continuous function and we do a comparison with observations and empirical models appeared in the literature to validate our approach.
