Based on the model described in [1], we present an analytical+numerical study of the resonance capture under Type-I migration for the Kepler-25 [2] and K2-24 [3] Kepler systems, both close to a 2/1 mean-motion resonance. We find that, depending on the flare index and the proximity to the central star, the average value of the period-ratio between two consecutive planets show a significant deviation with respect to the resonant nominal value, up to values well in agreement with the observations.
