DESCRIPTION:Gravitational instability (GI) is believed to be one of the ma
 in drivers of angular momentum transport in young protoplanetary discs. Th
 ese discs are often massive\, and the influence of their self-gravity play
 s a crucial role in their evolution. In this talk\, I will explore the con
 nection between protoplanetary disc kinematics and gravitational instabili
 ty\, highlighting how GI leaves distinct kinematic signatures. Properly in
 terpreting these perturbations provides valuable insights into the structu
 re and evolution of protoplanetary discs. I will present two case studies 
 — Elias 2-27 and AB Aur — demonstrating how our kinematic models accur
 ately capture the characteristics of these GI discs.
