Carnegie Supernova Project: kinky \(i\)-band light-curves of Type Ia supernovae

We present detailed investigation of a specific \(i\)-band light-curve feature in Type Ia supernovae (SNe Ia) using the rapid cadence and high signal-to-noise ratio light-curves obtained by the Carnegie Supernova Project. The feature is present in most SNe Ia and emerges a few days after the \(i\)-b...
