Dust formation is a research area in astrophysics that focuses on understanding the processes by which dust grains are formed in various astronomical environments, such as supernovae, planetary nebulae, and galaxies. Dust grains play a crucial role in the formation of stars and planetary systems, as they absorb and scatter light, provide sites for chemical reactions, and influence the thermal balance of their surrounding gas and plasma. Research in dust formation seeks to elucidate the physical and chemical conditions that lead to the creation of dust grains, as well as their impact on the evolution of galaxies and the universe as a whole.
