Circumstellar envelopes as a research area focus on the physical, chemical, and dynamical characterization of extended gaseous and dusty regions surrounding stars, particularly evolved objects such as asymptotic giant branch stars, red supergiants, and some massive young stellar objects. Work in this field investigates mass-loss processes, dust formation and growth, molecular chemistry, radiative transfer, and the interaction of stellar winds with the ambient medium. It integrates multiwavelength observations (from radio to infrared and optical) with hydrodynamic and magnetohydrodynamic modeling to constrain envelope morphology, kinematics, clumpiness, and temporal variability, thereby informing stellar evolution, feedback, and the enrichment of the interstellar medium.
