Transition disks are a specific type of protoplanetary disk surrounding young stars that are undergoing a transition phase in their evolution. These disks are characterized by a deficit of dust material in their inner regions, possibly indicating the formation of planets or other objects. Transition disks are of particular interest to astronomers studying planet formation, as they can provide valuable insights into the early stages of planetary systems. Researchers study the structure, composition, and evolution of transition disks to better understand the processes involved in planet formation and the diversity of planetary systems.
