Disk formation is a research area within the field of astrophysics and astronomy that focuses on understanding how planetary systems, including our own solar system, form from rotating disks of gas and dust around young stars. These disks are known as protoplanetary disks, and they play a crucial role in the formation of planets and other celestial bodies. Researchers study disk formation to gain insights into the processes that lead to the creation of planets, moons, comets, and other objects in our universe. By observing and analyzing protoplanetary disks around young stars, scientists can learn more about the conditions and mechanisms that govern the formation and evolution of planetary systems. Research in this area involves a combination of observational studies, theoretical modeling, and simulations to investigate the physical and chemical properties of protoplanetary disks and understand how these disks evolve over time to give rise to planetary systems. Disk formation research also has implications for our understanding of the origins of life on Earth and other planets.
