Stellar disks refer to the flattened, rotating components found in spiral and lenticular galaxies. These disks are composed of stars, gas, and dust, and play a crucial role in shaping the overall structure and dynamics of galaxies. Research in this area focuses on understanding the formation, evolution, and properties of stellar disks, as well as their interactions with other components of galaxies such as bulges and dark matter halos. Studying stellar disks can provide valuable insights into the processes driving galaxy evolution, including star formation, gas accretion, and the influence of mergers and interactions.
