We study tangential families, i.e. 1-parameter families of rays emanating tangentially from a curve. We give normal forms of generic tangential families under Left-Right equivalence and we show that their envelopes are smooth or have a second order self-tangency. We prove the stability of these envelopes under small tangential deformations, that is… (More)
